Heidi Klum and Paulina Porizkova will reportedly guest on an upcoming episode of 'Desperate Housewives.' The supermodels will play themselves in the episode, airing in March, when Gaby (Eva Longoria Parker) and Angie (Drea de Matteo) run into them in New York City. Somehow, we doubt they'll be on their best model behavior. [E!]

More casting news after the jump.

Ah, Season Four. You were so good to us, even though you were slightly shorted by that pesky writers strike. Lost wasn't as impacted as a lot of other shows because the creators had already gotten the okay to do three shorter seasons before any of this happened. Sure they lost a little bit of time, but not enough to have really impacted the show.

And Season Four gave us such pivotal moments. The introduction of the freighties, including some really good and interesting characters. The return of Michael. The identities of the Oceanic Six. An in-depth examination of what happened to them after the island in more flash forwards. The man in the cabin. Ben moves the island. And the identity of the man in the casket. So much happened in fourteen short episodes, but still that's not enough. To fill out the set, we've got two full discs of extras.

Lost's Marsha Thomason may have gotten more screen time in Wednesday's "Greatest Hits," but her character remains a mystery to viewers. In an interview with The Trades, the actress discussed her first scenes as Naomi, her previous TV roles, and getting along with the show's cast and crew. Here are the highlights:

• Thomason has known co-star Dominic Monaghan for a long time, and was glad that her first Lost scenes were with him.

Last week, Marsha Thomason made her debut on the ABC series Lost as Naomi the parachutist. Even though she didn't have much screen time in last week's episode, Thomason's role will expand in tonight's episode and is even said to drop a bombshell on the survivors. When spoilers about her role first leaked, it was said that the character would be a regular. It is unknown if she will in fact be a regular or a recurring cast member. One thing is sure, Marsha Thomason will appear in most, if not all, of the remaining episodes of the season and, if the fans respond better to her character than they did to Nikki and Paulo, she may still be around in Season 3.

Many Lost fans may wonder who Marsha Thomason is but Las Vegas fans know exactly who she is. Thomason was a regular on the NBC series for a few years until her character abruptly left the show.
