The upcoming father/son comedy flick "That's My Boy" hits theaters June 15th, and last night it had its premiere in Hollywood.

Leighton Meester, who plays Christina, the female lead in the film, hit the red carpet and showed off one of the things she obviously has to thank for that role— her good looks. In a tie-dye dress and black Jimmy Choo heels and reminded us just how hot she really is.

Meester may have to ramp up her Hollywood workload now that "Gossip Girl" will be heading into its final season.

"It's bittersweet," she recently told E! Online. "But at the same time, it's great to move on and do something different. Playing the same character for six years is great, but it's exciting to do other things and also just sleeping and spending time with my family."
