Kirsten Dunst fears she'll never find anyone to have children with.

The 30-year-old actress - who is currently dating 27-year-old actor Garrett Hedlund - is scared by the ''Peter Pan'' attitude of many of the guys she meets and can't see them ever being mature enough to settle down.

She told Psychologies magazine: ''I thought when I reached 30 I'd have a lot more figured out.

''But until you have a kid, you're just looking for your partner. And guys have a Peter Pan vibe.

''They're 35 and they behave like they're 25. That's what scares me about being in my 30s - not finding someone to have kids with.''

Kirsten recently admitted that as she gets older she prefers to be friends with someone before dating them because she can't rely on ''instant chemistry'' to help form a long lasting relationship.

She said: ''My experience is that as you get older you try to pick a partner who you're friends with. It's hard to find balance and that's not going to come with the 'instant chemistry' kind of people.''
