Paris HiltonParis HiltonParis Hilton has got a bit of a crush on someone.

But there's no need for her new boyf Matt Leinart to worry... the object of her affections is a girl - one of her best mates, in fact.

The heiress has been heaping praise on her NBF (new best friend), Rod Stewart's daughter Kimberly, and admitted having a crush on her.

"Kimberly is hysterical. She's six feet tall, blonde, beautiful and has luscious blue eyes," she told Top Of The Pops magazine.

She raved on: "She's hot. I feel so comfortable with her and I can just act like myself."

It seems Paris has come over all warm and fuzzy - she even had some kind words for her EBF (ex-best friend) Nicole Richie.

The two stars, who star together in reality TV show The Simple Life, have been feuding for months.

But Paris isn't the only one with an NBF - Nic is often seen stepping out with Lindsay Lohan and/ or Mischa Barton.
