James Van Der Beek will guest star on an upcoming episode of 'Law & Order: CI.'

According to TVLine, the 'Dawson's Creek' veteran will play Rex Tamlyn, described as an "overconfident, hard-partying playboy." The character is a partner in a Facebook-esque website that's devoted to hooking people up for fleeting romantic trysts.

Like 'The Social Network,' there's a lawsuit around the idea of the site, but with this case there are a few murders mixed in. It's 'Criminal Intent,' what do you expect? Thad and Trent Luckinbill also guest star.

Van Der Beek will appear in the ABC midseason comedy 'Apartment 23' as a fictionalized version of himself.

(S07E04) "I think, in a way, we all feel responsible." - Sean

Just when it looked like we were on our way to a major break-up, Nip/Tuck threw fans a curve ball last night as we head in to the series' final five episodes. For as much as Sean may despise Christian, what he's done, and how he acts, sticking with him for 25 years has left a scar -- Sean may see himself as the opposite of Christian, but the rest of the world views them as one and the same.

(S04E15) We've waited about three weeks to see this episode, since President Obama decided to inconvenience HIMYM fans by holding his first primetime press conference on the night this was originally supposed to air. Was "The Stinsons" worth the wait? Definitely. And not just because we met Barney's mom.

It was just plain ol' laugh-out-loud funny. And Bays and Thomas were able to explore how Barn's ability to deceive could be used for sentimental reasons as well as self-serving ones. It also gave us a chance to see Ted overact, Marshall call himself the runt of the family, and Lily and Robin hide under coats and loose tops.

(S05E07) "Knock it off!" - Gaby to a creepy, clingy and too generous Virginia

Last week, I mentioned how I thought the arrival of Gail O'Grady, Frances Conroy and Lily Tomlin spiced things up on Wisteria Lane. This week, they definitely brought on new spice because the three storylines got more complex and twisted. Sometimes, TV series push guest stars down our throats for sake of ratings (see Britney Spears on How I Met Your Mother for a recent example). However, this is not the case with the three actresses guesting on Desperate Housewives. Tomlin is especially a delight to see in her role as McCluskey's sister and Conroy, as I've mentioned last week, finally gives the Solises a reason to still get air time.

(S05E06) "When the time comes, an alibi would be nice." - Gaby

Sweeps is a time for closure, new twists, guest stars, and OMG!/WTF? moments. This week's episode of Desperate Housewives, which is the first November Sweeps installment of the series this season, definitely offered us new twists and guest stars thanks to the arrival of Gail O'Grady, Frances Conroy and Lily Tomlin. All three actresses will appear in a few episodes of the series and, as we saw in "There's Always a Woman," will be involved in some important way in the storylines.

The characters on Six Feet Under were fascinating to watch, but they often made horrible romantic choices. Even the couples that stood the test of time had their issues. Most of the truly memorable train wrecks didn't last, though. Here's a look back at some of the show's weirdest relationships.

Ruth Fisher and Arthur Martin - Ruth and Arthur's relationship was arguably the most awkward pairing in Six Feet Under history. Apart from the significant age difference, the relationship suffered from a lack of physical intimacy. You can't build a romance on nuzzling and spooning alone; it didn't take long for Ruth to figure that out. Ruth dumped Arthur, and things took a turn for the worse when she suddenly married George Sibley. Arthur showed his jealousy by arguing with George over the origins of the word "formica" and labeling his food. They finally parted ways after the "poo by mail" misunderstanding.

Fans of Six Feet Under were floored, when at the end "Ecotone" (the fourth to last episode of the series) Nate finally succumbed to his AVM and passed away. His death earned one of the few "end of episode epitaphs" featured on the show.

Fortunately for Nate and his family, everyone had a chance to say good-bye. Claire and David spent hours in the hospital room with him, as did Ruth. Even Brenda visited, despite knowing about the affair with Maggie - until Nate says no more; we're done.

As fans, we cried. We mourned. We couldn't imagine the final three episodes of one HBO's finest programs without it's main player. Of course, we knew he'd be back - dead. That was a given, but it's still not the same. Little did we know what was in store for us.

A whole lot more crying.

(S03E08) Two words: Jeanne Tripplehorn. Keith's paintball revenge was his finest moment on the show as far as I'm concerned. The Fishers and Diazes played against type and became people of action, if only for a short while. David and Keith settled their differences on the battlefield, Ruth made several uncomfortable moves on Arthur, and Lisa sized up her competition. Petrarch, head lice, and polygamy also came into play.

Bravo has the exclusive rights to air all 63 episodes of the HBO hit series, Six Feet Under. Bravo says it'll start airing the entire series sometime this year, possibly this fall, although the announcement doesn't give an exact date. HBO refuses to say exactly how much the syndication deal is worth but this report puts it at $15 million, or $250,000 an episode. HBO originally pimped out Six Feet Under for $450,000 but that was a little too rich for other networks' blood. As with Sex and the City, HBO has given Bravo the go-ahead to clean up the language and video.
