Mila Kunis has no time for dating.

The 'Ted' actress - who is rumored to be romancing Ashton Kutcher - insists she is single because she is busy and also finds the idea of going out with someone for the first time daunting.

She said: ''First, I have to find some time to start seeing a guy, which is tough for me because I'm terrible on dates and I get nervous and don't always feel comfortable or natural in those situations. I don't know why that is.''

Mila, who was in a relationship with Macaulay Culkin from 2002 to 2010, admits being famous can make things difficult for finding a boyfriend, which is why she thinks dating another actor is easier.

She explained to heat magazine: ''It does sometimes change the dynamic, in the sense that you're more well known and people presuppose more about you because they've seen your work and maybe read things about you.

''But usually you meet people in the same business, so you're not feeling awkward if you or the guy you met has just had a big film out, or whatever.''
