The 46-year-old actress also grabbed Choice Actress Award in a romantic comedy for "The Proposal", for which she also shared the Choice Dance award with Betty White.

"I don't know if you should bring attention to this. Some things are better left unsaid. It's been awhile since I was a teen," Bullock said. "I'm so blessed and lucky. The Blind Side – I got to meet so many good people, so many good lessons I took away from it."

The ceremony of Teen Choice Awards 2010 was held at the Universal Amphitheater in Los Angeles. The host, pop singer Katy Perry kicked off the night with her latest song “Teenage Dream."
