Socialite Paris Hilton has dismissed reports she is planning to adopt four blonde babies, branding the rumours "retarded". The Simple Life star was allegedly planning to adopt the children with sexy Entourage star Adrian Grenier - but Hilton insists the actor is "just a friend". She tells People.com, "Someone just said that I'm adopting four blonde babies. That's retarded. No, I'm not. "(Grenier and I are) totally just friends. We met a couple years ago and we've stayed friends. He's been like kind of a mentor to me, teaching me about the environment and what I can do. "I think it's cool to talk to someone in Los Angeles who has more to talk about than all this artificial crap people talk about. It's nice to talk to someone who's real."
