Last night's CBS annual summer party was given a healthy dose of glamour by the 90210 girls.

AnnaLynne McCord led the way in a studded mini skirt and sky high heels. She'd also had a sleek new hair do for the event and it's one we're coveting ourselves!

AnnaLynne's co-star, Shenae Grimes wasn't about to be out done, opting for a gorgeous Grecian inspired green dress.

Also in attendence was High School Musical star Ashley Tisdale who wore a white mini dress and those bow detailed Louboutin's.

Who do you think looked the best on the green carpet?!
