I realize that celebrities don't always have an easy time of it. They're hounded by photographers, work crazy hours, spend time away from their families while on location, and never know when their current gig might end through no fault of their own.

But, you know what? The rest of us don't have an easy time of it either. Sure, most of us don't have photographers hounding us at every turn, but we work crazy hours, spend time away from our families working, and never know when OUR current gigs might end through no fault of our own.

So it always drives me a little batty when celebrities whine about having to work long hours and such, like Katherine Heigl did on the Late Show with David Letterman and other talk shows -- especially since the aforementioned long day was the direct result of accommodating her schedule while promoting her new film The Ugly Truth.

TBS has put an order in for 46 more episodes of Tyler Perry's 'House of Payne,' bringing its grand total to a whopping 176 in just two years.

Also in the news today: T.R. Knight explains his 'Grey's Anatomy' exit, while the Emmy submission tapes get their big reveal.

The Internet has been all atwitter since Dominic Monaghan, aka the dearly departed Charlie Pace on Lost, showed up in a new ABC promo. In it, Dominic/Charlie is playing Foosball with current and upcoming ABC stars, including Patrick Dempsey from Grey's Anatomy and Courteney Cox from the upcoming Cougar Town. Jason Hughes theorizes that this could very well mean that Monaghan is returning to Lost next season.

This of course, is not out of the realm of possibility: death, after all, rarely means goodbye on Lost. On the other hand, it's not unheard of for stars who have exited the island to find themselves on other ABC shows (see: Harold Perrineau on The Unusuals). So which is it? Well, that crafty cad Michael Ausiello thinks he has the answer. See what spoilers ABC execs shared with him after the jump.

This season's Grey's Anatomy ended on quite a tense note, with both George and Izzie's lives hanging in the balance. Izzie, of course, had been battling cancer for most of the season, while George was hit and then dragged down the street by a bus after pushing a young woman out of the way. The episode ended with both characters flat-lining, leaving fans to agonize for months over who survives. Now, however, it looks as though we may have an answer.

Both of the actors in question, Katherine Heigl and T.R. Knight, have made no secret of their displeasure with the show and their respective storylines as of late. Heigl pulled her name out of Emmy consideration last year, while Knight reportedly asked to be let out of his contract this past December. The behind-the-scenes grumbling has led to a great deal of speculation about who may live and who may die, but now E! Online's Marc Malkin is reporting that he knows the fate of at least one of those two characters.

This week we have: Glee, 24, Melrose Place, Grey's Anatomy, Chuck, Scrubs and Fringe (SPOILERS FOLLOW!)

The 99th episode of Grey's Anatomy has come and past and the last five minutes got to me. There's something gratifying about having all the storylines set to music and every other character in tears. It's definitely setting up for the big 100.

I was a little tense about the storyline of the little girl shooter, but it was written in taste. The girl was creepy since she reminded me of every stereotypical horror movie child, silently staring at the lead characters. Why is Meredith often paired up with killers? I get it, the little girl is supposed to parallel Meredith's relationship with her father or the chief, but she could have just been an ignored daughter and not a shooter whose mother probably handed her the gun.

There a few news bites from several of the Grey's Anatomy actors pre-scoured for your convenience. It's kind of odd reading about these people outside of their characters, but it's true: they are real people. We got some news from Patrick Dempsey, Chandra Wilson, T.R. Knight, and more:

Chandra Wilson to join cast of Chicago - This one's a little old, but noteworthy. Chandra Wilson, better known as Miranda Bailey, will be playing Matron Mama Morton in the musical Chicago starting June 8th and ending July 5, 2009. It's great seeing Wilson play another really strong character; I've never heard her singing chops, but she has a background in musicals, so I'm not doubting it.

As a TV blogger, I've got to say this whole drama is exasperating. I'm a little tired of writing about Heigl, Knight and Shonda. I was even on the fence about choosing the "Reality-Free" category for this post, since the backstage hijinks of Grey's Anatomy could give any reality show a run for their money.

On Wednesday, I reported that James Pickens let slip that Heigl and Knight were leaving Grey's Anatomy. Yeah, that's not true, according to Shonda Rhimes. Rhimes says that rumors spread as fact and that Pickens' words were taken out of context. Heigl and Knight are not leaving Grey's Anatomy, and that's a fact, again, according to Rhimes. Do I smell a cover (your ass) up, Shonda?

The original rumor stated that it wasn't a done deal because they were trying to negotiate story arcs for the characters for next season. That's a pretty detailed fact to be "just a rumor," if you ask me.

It will be very interesting to see what actually does take place when all is said and done. I'm exhausted, and I'm really starting to wonder if I'll ever care as much about Izzie and George in proportion to the amount of will-they-won't-they that has gone on.

You know, sometimes I think Grey's Anatomy isn't so much about the drama on screen, since the behind-the-scenes drama always seems to trump the fictional stuff. Is the Meredith / Derek love-fest as interesting as the Heigl / Knight quit-fest? It seems that the entire cast of Grey's is suffering from a medical condition: a giant, gaping hole in the center of their face that just doesn't quit gabbing.

Just when the whole Isaiah Washington big-mouth scandal and subsequent firing finally blows over, we begin hearing rumors that T.R. Knight is going to be let go. Then we are assured that isn't the case, only to hear that Knight is very vocal in begging to be let go.

Katherine Heigl couldn't let Knight get all the limelight, though; it started with her obnoxious behavior when she pulled her name for consideration of an Emmy nomination, blaming the writers for her crappy storylines. Then it morphed to her sleeping-with-the-dead-guy storyline (she asked for it!) which only made us think more about Izzie leaving the show with a fatal condition. We know you think you're better than TV, Katherine, now shut up about it.

"The pager is sacred. Sacred sparkle." -- Izzie

A sparkly pager, some quick-drying cement, and a field of candles all play into tonight's 2-hour episode -- the Season Four finale of Grey's Anatomy. Has it really been only four seasons? Because it seems like so much more.

Anyway, tonight we learn a little more about some of the interns' history. For one thing, via a therapy session (and why can't I have Amy Madigan as my therapist?), we learn that young Meredith saw her mom slit her wrists, then had to wait for her to pass out before calling 911.

Meredith says her mom wanted to die, but by the end of the episode, she figures out that she really didn't want to die. Being a brilliant surgeon, her mom would have known the faster road to death entailed slitting her carotid artery.

Apparently there have been rumors swirling that T.R. Knight, who plays George O'Malley on Grey's Anatomy, is gay. Today, Knight released a statement to People magazine, saying he is gay and "I hope the fact that I'm gay isn't the most interesting part of me." People's headline is grotesque: EXCLUSIVE: Grey's Anatomy Star T.R. Knight Confirms He's Gay.

WTF?

Why is this a big deal? Does it change the fact that he does a spectacular job playing the role of George, who is madly in love with Meredith Grey? I feel sorry for the guy because it sounds like he was hounded and badgered about something that really shouldn't matter to anyone.
