The last time Jeremy Piven appeared on 'The Tonight Show' (Weeknights, 11:35PM ET on NBC), he played a prank on one of the pages -- who did remind us a bit of Kenneth from '30 Rock' -- that had the poor guy standing in the hall terrified.

Piven pretended to have a full-blown Hollywood superstar tantrum about there being sushi in his dressing room. But afterward he felt bad about it, so he decided to help the guy out with his dreams of being in show business.

He pulled some strings down at 'Entourage' and managed to get the guy a part on the show, and it is definitely something to see. Jay Leno managed to squeeze in the page's entire scene during 'The Tonight Show,' with an arrow to help us identify him. Taking Hollywood by storm, this guy!

Jeremy Piven may not be giving himself enough credit. On 'Late Show' (Weeknights, 11:37PM ET on CBS), he and David Letterman were talking about dancing. Piven said he had mastered one dance move in the late '80s, 'The Worm.'

Letterman kept hinting around that he wanted Piven to give a demonstration, but Piven wasn't going for it. "If I did it now I'd hurt myself."

But then the crowd got behind Letterman, and put the pressure on Piven. "Can't really disappoint them now," Letterman goaded about the growing clamor from the studio audience.

"I'll warm up and we'll see what we got," Piven said. He then dropped into the splits, and we're talking all the way to the ground. This was impressive for two reaons. One, that he had that kind of flexibility, and two, that his pants had that kind of flexibility.

We know where Ellen DeGeneres is -- when she's not hosting her Daytime Emmy-winning 'The Ellen DeGeneres Show,' she's with Simon, Randy and Kara at the 'American Idol' judges table.

But what happened to the funny lady's former TV cohorts from her Emmy-winning 1994-98 ABC sitcom 'Ellen' (which included the famous 'Puppy Episode,' where DeGeneres' character, Ellen Morgan, announced she was gay) and her short-lived 2001-02 CBS comedy 'The Ellen Show'?

Where are they now? Check it out after the jump.

Need a break from all the reality TV stars? The crew over at Moviefone's Inside Movies has just what you need.

Woody Allen has always had a thing for younger women, and this time it's an ex-supermodel (Carla Bruni-Sarkozy). However, his only interest in her is for a role in an upcoming film.

On tonight's hilarious second episode of Community, we see the first appearance of Ken Jeong, who's joining the cast as Spanish professor Señor Chang. Chang has a bit of a chip on his shoulder because he always has to fight against Asian stereotypes.

He's a welcome addition to the cast, and he's been having a hell of a summer. Besides his memorable turn in the massive summer hit The Hangover, he was also in All About Steve and The Goods: Live Hard, Sell Hard. To promote the latter movie, Jeong and co-star Jeremy Piven bounced around the ring on WWE Raw in August. Imagine a tiny guy like the 40-year-old Jeong trading blows with huge wrestlers and you can see the comic potential.

When I talked to Jeong at NBC's party at the TCA press tour, we were interrupted by WWE's The Miz, and the exchange between them was just too funny for me to keep on my hard drive. Audio is after the jump.

So, last night's episode of 'Big Brother 11' was filled with the usual petty arguments, inane conversations about spider anatomy and endless strategizing ... when all of a sudden Jeremy Piven stopped by.

Yes, that Jeremy Piven. The three-time Emmy winner from 'Entourage randomly showed up at the 'BB' house and cracked jokes with the houseguests. Was Piven just in the neighborhood? Of course not. He delivered some, ah, interesting news: The luxury challenge reward would be a screening of his new movie, 'The Goods: Live Hard, Sell Hard.'

Groan. Really, Piven, this is how low you'll go?

The answer.

When it comes to the Primetime Emmy nominations, there are scads of terrific supporting performances to choose from in the comedy field. The difficulty is narrowing it down to just six actors and six actresses (which is better than last year's five each). Maybe the Emmys should take a page from the Academy Awards and double the number of nominations -- this year's Best Picture will include ten noms. That's not going to happen, but that doesn't mean my wish list discussion can't mention all those worthy comedy performers.

Last year's comedy winners, Jean Smart for Samantha Who? and Jeremy Piven for Entourage, were both multiple winners. In Jean's case, it wasn't all for the same role, but Jeremy has been pulling a John Larroquette/Don Knotts in this category. (Larroquette and Knotts dominated this category; the former winning for Night Court from 1985-88, while Knotts won five times for The Andy Griffith Show from 1961-67). My wish list would start by shaking things up.

E!'s Watch With Kristen is reporting that Zac Efron will be joining the Entourage gang for season six. Well, maybe not exactly joining the gang, but at least making a cameo on the HBO show.

Ok, so the question is, will he be playing himself? One of Ari Gold's newest It-Guys? An excitable young actor who tussles with Johnny Drama? My guess is that Efron will be playing himself, because he's becoming the Next Big Thing in Hollywood -- if he isn't already there.

And it just makes sense, because so many other stars have appeared as themselves on the show; notably, James Woods, though I've always wondered if he's as hot-headed as they make him out to be on the show. If so, he has quite the sense of humor about himself.

Ten years after ABC prematurely cancelled Rob Thomas' dramedy Cupid, the alphabet net has decided to give it another go. The new version of the show, which premieres Tuesday at 10 PM ET, now stars Sarah Paulson and Bobby Cannavale in the roles originated by Paula Marshall and Jeremy Piven, respectively.

The premise is the same: Trevor Pierce claims to be Cupid, exiled from Mt. Olympus, and he needs to find true love for 100 couples before he is allowed back home. After Trevor is arrested for one of his stunts and sent to a psychological hospital, singles self-help guru Dr. Claire McCrae is assigned to keep track of him as he makes his way in the outside world. This time around, the show is set in the fast paced and cynical world of New York, complete with all the modern touches of dating in the late '00s (Maybe Cupid will have a Twitter account).

I spoke to the stars of the new Cupid last week. While I was on the phone, I asked Paulson about what happened on her previous series, Studio 60. I got a pretty interesting response...

Here's an appointment to the President-elect Barack Obama's new administration that should really make Hardball's Chris Matthews happy. He's hired Ari Gold's brother -- sort of. Rep. Rahm Emanuel, has accepted the job as White House Chief of Staff, and the Congressman's brother Ari Emanuel is the inspiration for Jeremy Piven's character Ari Gold on Entourage.

Just like Ari on HBO, Ari Emanuel is Hollywood's toughest agent and Endeavor Talent Agency is the tops in the business. Ari's brother Rahm has a reputation for being just as ambitious, aggressive and forceful. He likes to play hardball and has been known to twist arms and bust heads, metaphorically, to get things done.

The name Jordan Belfi might not mean much to you, but if you watch Entourage, you absolutely know Adam Davies. And, if Belfi's done his job right, you probably really hate the guy.

As the best-dressed nemesis on TV, Davies is the super-agent foil to most of Ari Gold's (Jeremy Piven) plans and schemes. And in a particularly conniving episode (airing Sun., Sept. 21 at 10PM), the Davies/Gold smack down reaches new heights. Or lows, depending on how you see it.

Belfi talked to us about his character's underhanded ways, his most devoted fans and why watching Gordon Ramsay vomit means must-see-TV in his house.

Over at the L.A. Times, Tom O'Neil has put together two teams to predict the Emmys. One consists of writers who cover TV, including our pal from AOL, Maggie Furlong. The other is filled with award nuts, like O'Neil. The teams found a lot of common ground, with overwhelming agreement on Mad Men for Best Drama and 30 Rock for Best Comedy. They also seem pretty set on Glenn Close (Damages) for Best Actress, Drama and Alec Baldwin (30 Rock) for Best Actor, Comedy.

Those all sound like reasonably safe bets. Things get a little more interesting when you look at some of the other categories. Best Actor, Drama looks to be a three way race between Jon Hamm (Mad Men), Hugh Laurie (House), and James Spader (Boston Legal). All solid choices, to be sure, but the most surprising part of the category is that Bryan Cranston (Breaking Bad), who should win, only garnered one vote. Read on past the jump for more of the categories.

Don't get him wrong; Jon Cryer is thrilled to be nominated for an Emmy again. This is his third nomination as Outstanding Supporting Actor in a Comedy Series as Alan Harper, the sad sack, divorced brother of Charlie Sheen on Two and a Half Men. In 2006 and 2007, he lost to Jeremy Piven, Ari Gold on Entourage, and Jon Cryer is ticked off: "Laugh all you want, [he] is my nemesis. He's a force of nature."

If it's not Piven -- again! -- Jon has another nemesis lined up: "I think this time Neil Patrick Harris (Barney on How I Met Your Mother) will win."

Cryer is good natured about his chances and not seriously miffed. He's planning to bring his new wife, entertainment reporter Lisa Joyner. "When we heard the news, she was thrilled for a moment, then filled with dread as she started to worry about what she'll wear. But she'll be there with me -- or I'll be very lonely."
