The actress got weird with her dog.
Whoaaasomanycelebrities.  The CW, CBS and Showtime 2012 Summer TCA party got underway last night (July 29th) at The Beverly Hilton Hotel, inviting many a starlet to dress up in red carpet finery.

Hart Of Dixie’s Rachel Bilson looked like a cupcake and oh-so-Summer-Roberts-ish in a sleveless blouse and pants that only she could pull off (great detail, though it might make yours truly look a bit “hippy”).

Tyra Banks looked tres svelte in her LBD, while Kat Dennings really pushed the girls together for a night out.  Bravah! 

Banks is preparing for a new season of America’s Next Top Model, welcoming new judge Kelly Cutrone and bidding farewell to former colleague Nigel Barker.  “I’m happy for Nigel.  I mean, come on. He’s amazing and he built ‘Top Model’ with us so I can only wish him success,” Banks said at the TCAs, according to Access Hollywood.  “We’re in 170 countries and 24 formats.”

I am totes digging Lucy Lius J. Mendel dress, BTW.  Also, totally loving Jaime King’s Stella McCartney get-up.

So…thoughts on the red carpet?  Who wore what best?
