Jude LawJude Law reportedly finished with Sienna Miller because he was jealous of her new friendship with Sean Penn.

A friend of Jude’s told the News of the World: “”Things have always been up and down between them, but recently Jude took real issue with the close bond that has developed between Sienna and Sean.”

Jude became friends with Sean when he filmed Breaking and Entering with Sean’s wife, Robin Wright Penn and introduced his then-girlfriend Sienna to Sean.

The friend added: “It was [Jude] that had introduced [Sienna and Sean], but suddenly he felt left out and suspicious - and didn’t like it. Sienna is a fun girl and forms close bonds with most men she meets. But Jude didn’t like the way they were too close.”

“It’s not as if he’s a jealous man but their friendship wasn’t healthy. He just had to end it.”
