BRITISH actor Jude Law is engaged to actress Sienna Miller after proposing to her on Christmas Day, according to tabloids.

"It's true they are engaged," a spokeswoman for the couple told The Sun. "Jude has bought Sienna a big cluster diamond ring.
"He asked Sienna to marry him on Christmas Day. They spent Christmas together in England. They then headed to the Indian Ocean. They have told their families the news and they're thrilled, as are Jude's children."

Law met Miller 23, whilst filming the remake of the 1960’s hit Alfie. He has three young children by his ex-wife, British fashion designer and actress Sadie Frost.

Law, 32, first gained wide notice with movie audiences and won an Oscar nomination playing a spoiled young playboy and the object of Matt Damon's obsession in The Talented Mr Ripley.

He earned a second Academy Award nomination for his role as a Confederate deserter in the popular Civil War drama Cold Mountain.
