Television’s style sirens hit Day 1 of the 2010 Summer TCA Press Tour at the Beverly Hilton Hotel on Wednesday, walking the green carpet in sizzling and fizzling fashions. AnnaLynne McCord and Ashley Tisdale dominated the trendy tube set, both clad in super sexy looks from the hottest designers.

AnnaLynne showed off her flawless figure in a skintight Rock & Republic mini, which featured an embellished skirt.  The 90210 vixen paired the lowcut number with her fave Christian Louboutin mesh heels and a metallic, geometric box clutch.

Ashley sizzled in an all-white look from Bodyamr.  The High School Musical star looked super sophisticated in the crafty ensemble, pairing it with Christian Louboutin Clou Noeud heels and a reptilian clutch.

Sara Gilbert has definitely matured since her Roseanne days, and though we loved her baby blue, leather lapeled blazer, we weren’t crazy about her overall putrid color scheme. Gabourey Sidibe rocked a Precious orange frock, while Friday Night Lights beauty Jurnee Smollet got glam in a zipper-front LBD.
