Paris HiltonParis HiltonSo, who is Paris Hilton's latest enemy?

The socialite heiress has had her fair share of bust-ups over the years...

But this particular lady is none too pleased about rumours that Paris has been hitting on her man.

The girl in question?

It's footballer's fiancee Elen Rives, partner of Chelsea's golden boy Frank Lampard and mum to the couple's six-month-old little girl, Luna.

She's not happy following claims that Paris followed Frank to two parties after she presented a gong at the Brit Awards.

And Paris giving Frank her mobile apparently didn't go down well either.

According to the Daily Mirror, Elen confided to a friend: "Frank obviously only has eyes for me.

"This Paris Hilton might be used to getting what she wants but this is one man she can't have. She might have millions but she's no match for me.

The friend added: "Elen has always said she's lucky that Frank's not a party animal who's always pictured falling out of clubs with some bimbo on his arm."

Miaowww.

Paris is said to be happily coupled up with her man Stavros Niarchos, so perhaps an innocent chat about the off-side rule has just been blown out of all proportion.
