"But I'm Really Not A Slut"

Though she’s reported to have gotten quite “chummy” with Diddy on several ocassions, Sienna Miller is denying that the pair’s relationship is more than just friendly.

Says Slutty, “I am in love with someone but not Puff Daddy. He`s just a good friend. Anyway he has a beautiful girlfriend.”

Sienna will let her friends get to third base and her “good friends” go all the way.

She’s just friendly like that!
