Sienna MillerIt seems like a bit of history repeating itself for Sienna Miller and relationships: she met Jude Law on the set of Alfie and now it looks like she’s started seeing Factory Girl co-star Hayden Christensen.

The pair have been spotted kissing in a car while visiting Hayden’s parents in Canada - but it might all it seems to be.

A friend of Sienna’s has told the Daily Mail: “Hayden was a brilliant shoulder to cry on when she finally split from Jude Law.”

“Sienna is quite flirty and their relationship became something more. Hayden is besotted with Sienna but I’m not sure she totally reciprocates his feelings.”

“Ever since they stopped filming Factory Girl he has been calling and texting her - he thinks he’s in love.”
