Lindsay loves Wilmer

Teen movie star Lindsay Lohan has confirmed she's dating actor Wilmer ValderramaA - but she doesn't know how serious the relationship is going to become.

The Freaky Friday actress, 18, has secretly been dating the 24-year-old That 70's Show star since the beginning of 2004, while denying romantic links to him.

But in a new Rolling Stone interview, Lohan admits she's in love with the actor, who has "been there for me with all this family s**t going on," referring to the recent arrest of her father Michael on fraud and assault charges.

She says of Valderrama: "If this matures into a serious relationship, he'll be my first real boyfriend."

Although, Lohan admits the attention her boyfriend gets from Los Angeles party girls makes her worry about the future of their romance.

She explains: "It's hard when we go out. They'll (girls) seriously hit on him right in front of me. I'm already insecure, and there are a lot of pretty girls in Los Angeles. It makes me feel bad."
