Though it's been four years since the first film in the comedy series debuted back in 2009, the 43-year-old actress looks just as good as she did in her first appearance in the trilogy—and she was dressed to prove it!
The blond beauty showed off her enviable figure in a body-hugging teal Herve L. Leroux dress with a plunging neckline that brought up the va-va-voom volume at the premiere and convinced us she's just as hot in a gown as she is in a bikini.
And because she's a red carpet pro, Graham made sure to bring out the bling, throwing on an elegant statement neck and cuffs that added just the right amount of sparkle.
