Cast updates: J-Hud joins Sex movie

Life is moving fast for Jennifer Hudson. The entertainer and former American Idol contestant is living proof that there is a career after reality television.

After finishing seventh in the third season of the reality singing show, Hudson auditioned for a role in the music extravaganza Dreamgirls, costarring with divas Beyoncé Knowles and Eddie Murphy. She stole every scene she was in and was immediately praised for her performance by critics, but her real moment was at this year's Academy Awards show, where she won the Oscar for Best Actress in Supporting Role.

Next, she'll appear in another diva-licious film, according to The Hollywood Reporter. Hudson has joined the cast of the big-screen version of Sex and the City, which begins filming for New Line Cinema next week in the Big Apple.

The 25-year-old (she'll be 26 tomorrow) will play Carrie Bradshaw's (Sarah Jessica Parker) assistant. The movie currently has a 2008 release date.

Back on the small screen, former Saturday Night Live cast member Chris Parnell has found a new gig. The funnyman has joined the midseason ABC comedy Miss/Guided, says The Hollywood Reporter.

Miss/Guided stars Arrested Development's Judy Greer as a guidance counselor at the high school she once attended. Parnell will play a "rival guidance counselor" (how does that work?) named Bruce.

Parnell was half of the wildly successful viral video Lazy Sunday, which saw him rap alongside Andy Samberg about buying pastries while en route to a summer blockbuster. Since leaving SNL, Parnell has filmed parts in several movies and was featured in a recurring role on 30 Rock, the NBC comedy from fellow SNL alum Tina Fey.
