Meet Lydia Hearst, 'Gossip Girl's' new Queen 'B!'

What sexy, blond socialite-model-heiress-actress will play a new Queen Bee on "Gossip Girl?"

NOT Paris Hilton, praise the lord.

The new "B" on the block is Lydia Hearst, heir to the Hearst fortune, daughter of Patricia Hearst and a young lady you could say was literally born for this show. A spokesperson for the CW confirmed that Hearst is shooting scenes today and that her episode airs May 19.

According to Page Six, Lydia flew back from London to start rehearsals for the CW's salacious and sexy series. Word is that Hearst just joined the prestigious Gersh Agency for acting and they landed her a small role on the hit teen show's finale.

A source said, "Being young, rich and beautiful, I guess it was fated that Lydia should join the cast, but I don't think she'll be playing a good girl."

I sure hope not; one good girl is enough. Serena is so sweet, she makes my teeth hurt.

Go, Lydia! We need more backstabbing "B's" on "Girl."

Even more new faces next week: Former "Buffy the Vampire Slayer" babe Michelle Trachtenberg appears as Georgina Sparks, a girl from Serena's past who threatens her social position. And Jesse Swenson, a new hunk from Broadway, will catch Jenny's roving eye!

Gosh, it's so hard to keep up with all this. ...

XOXO
