Taylor Lautner couldn't speak when he met Jessica Alba.

The 'Twilight' hunk has had a crush on the screen beauty since he was 10 and was left completely tongue-tied when he was introduced the 'Sin City' star at a Super Bowl match.

When quizzed on who his dream woman is, Taylor said: ''Jessica Alba. I've wanted to marry her since I was 10, but it's not looking good because she's married and has two kids. The first time I met her was at a Super Bowl. I was so nervous I could hardly talk. I felt so stupid.''

The single actor is looking for love and says he likes laid back and fun-loving girls who he can trust not to be affected by his showbiz lifestyle.

Taylor, 21, explained to more! magazine: ''Trust is way up there, as is loyalty. Apart from that, somebody who can just be herself and have fun. I don't like people who put on an act. I like people who can relax, let their hair down, and have a good time.''

Jessica has been married to producer Cash Warren since 2008 and they have two daughters Honor and Haven.
