She said recently: "People say the most horrible things to me like 'slut' and 'slag' and it upsets me because I'm not like that.

"I've never had a one stand in my life. I was in a relationship [with Jude Law] more or less for the five years since I was 20, and sometimes people forget this.”

“I know how to let it go over my head, but then sometimes you do question why people are saying it. But it’s not true.”

Sienna is currently dating Jamie Burke but has been previously linked to Hayden Christensen and Josh Hartnett as well as Jude.
