Justin Timberlake has a lot in common with his 'Shrek' character.The singer-and-actor could relate to his animated character Artie in 'Shrek the Third' - because they are both "uncool" and hated school. Justin, 26, told Bliss magazine: "My character in the film is not cool. He's a bright-eyed kid who's been told his whole life he's a loser, but he gets the opportunity to grow."When I was a kid, I felt I didn't fit in and didn't enjoy school. That's how I was able to play Artie because he doesn't fit in that much. I was a good student, but school wasn't awesome for me and I felt bored."'Shrek the Third' is Justin's debut role in an animated movie.The 'Sexy Back' singer recently confessed he enjoyed making films, but has no intention to become a full-time film star. He said: "I don't aspire to be a movie star - I get enough attention."I always wanted to act but I never really had the courage. I thought I wasn't going to get the opportunity to do it the way I wanted to do it."
