Annalynne McCord: Sexy in Vegas

Annalynne McCord stripped down on Saturday night in Vegas and showed the lucky partygoers why she’s the resident hottie on the new 90210.

The skinny starlet hosted an event at the Treasure Island Hotel and Casino with the cast of ‘Sirens of TI.’

Lucky for her, she’s 21, single, and has a smokin’ hot figure.

Check out the pictures from her trip to the City of Sin!
