Drew Barrymore (in Akris) put the squeeze on pal Cameron Diaz (in Victoria Beckham) after presenting her with the female star of the year award at CinemaCon in Las Vegas. “It’s never been about anything but being true to myself and having a great time,” Diaz told Extra when asked to share the secret to her success. “Making movies isn’t easy but it’s a lot of fun!” American Idol alum Carrie Underwood celebrated her movie debut at the Hollywood premiere of Soul Surfer, while Vanessa Hudgens, Abbie Cornish and the other sexy stars of Sucker Punch hit the red carpet in London for the UK release of their action flick.
