Jude Law surprises Sienna Miller with diamond ring in grand piano

London: Actor Jude Law surprised girlfriend Sienna Miller by gifting her a grand piano with a sapphire-diamond ring hidden inside.

By gifting sparkling USD 20,183 ring, Law has sparked rumours that they would get married in 2011. "She wept after opening up the piano lid and discovering a wooden box - made from the same wood as the piano - containing a diamond and sapphire ring," mirror.co.uk quoted a source close to the pair as saying. "Jude would love to make Sienna his wife before next year is out. Family and close friends are expecting a save-the-date card any time soon," a friend of the actor said. IANS
