Paris Hilton has her sights set on a regal Best Friend Forever - she's hit it off with British Royal Prince Harry's girlfriend.

The Social Life star met Chelsy Davy on a night out in London last month - and the socialite was enraptured with her fellow blonde.

She says, "Harry's girlfriend Chelsy was absolutely stunning and such a sweetheart. We chatted for ages. Prince William and Prince Harry were very nice and down-to-earth."

And Hilton isn't the first celebrity to be in awe of Davy - troubled singer Amy Winehouse is allegedly eager to take her for a night on the town.
