Jude Law is set to propose to Sienna Miller.

The 'Alfie' actor - who first got engaged to 'Factory Girl' star Sienna in 2004 - has rekindled his romance with the actress in recent months and is now ready to make her his fiancee again.

A source said: "Sienna was always the one. And now she is back in his life he never wants to let her go again.

"Jude did some serious thinking over Christmas in Britain with his ex-wife Sadie and the kids. And he realises just how important family life is to him.

"He needs a good woman to look after him. Sienna's fed up of the single life and wants to be with Jude for good."

Sienna's family are believed to be preparing themselves for a big announcement in the coming weeks.

The source added to the Daily Mirror newspaper: "It's only a matter of time before Jude pops the question. He and Sienna have never been happier together."

Jude and Sienna spent the festive period on the Caribbean island of Barbados together with his three children, Rafferty, Iris and Rudy, from his marriage to Sadie.

Last year, Jude became a father for the fourth time after American model Samantha Burke fell pregnant following a brief relationship.
