Blake Lively Brings 'Green Lantern' to CinemaCon

Blake Lively steps out in Dolce & Gabbana for a Warner Bros. Pictures presentation at CinemaCon 2011, held at Caesars Palace on Thursday (March 31) in Las Vegas.

The 23-year-old actress chatted about her upcoming film, The Green Lantern!

Blake will be honored as Breakthrough Performer at the conference!

Although she said she’s very excited for her role as Carol Ferris in the film, Blake said she’s nervous about making sure everything’s perfect for the film’s fans!

“My bodyguard, who is six-seven and very serious and doesn’t speak much, pulled me aside — I thought it was a security matter. He said. ‘You have to be sure your hair is brown.’ I said, ‘Yeah, I would assume so but we haven’t done it.’ He said, ‘Please trust me, make your hair brown. I don’t want the responsibility of fan boys attacking you at a convention,’” Blake shared (via Variety).
