Blake Lively was all smiles at the world premiere of her latest flick, 'Green Lantern,' Wednesday night.

According to Just Jared, the 'Gossip Girl' star wore a sheer white Chanel Couture gown as she worked the red carpet at the famous Grauman's Chinese Theater in Los Angeles.

Co-star Ryan Reynolds was also on hand at the premiere to greet fans and celebrate the action-packed film, which opens Friday.

Lively stopped by 'The Today Show' earlier this week and talked to host Matt Lauer about why her character in the film, Carol Ferris, is not your run-of-the-mill superhero girlfriend, saying she's one tough cookie to Reynold's Hal Jordan/Green Lantern.
