Tyra Banks Joining Gossip Girl

Tyra Banks is ready for her close-up!

The America's Next Top Model host will guest star on one episode of Gossip Girl's upcoming third season, her rep confirms to Usmagazine.com.

Banks will play Ursula Nyquist, a larger-than-life actress who Serena (played by Blake Lively) must control at the premiere of her latest movie, her rep tells Us.

The episode will air Oct. 5 at 9 p.m. EST.

The former supermodel isn't the only star who'll be spotted on the Upper East Side.

Hilary Duff signed on for a multi-episode story arc -- she'll be playing a movie star who enrolls at NYU and rooms with Jessica Szohr's character, Vanessa -- earlier this month.
