Jude Law and Sienna Miller reunite?

Jude Law and Sienna Miller have reportedly reunited.

The couple, who began their romance on the set of Alfie in 2004 but split two years later after Law admitted to an affair with his children's nanny, are said to have met secretly in New York on several occasions.

A source told Now: "Sienna and Jude have met up a few times and got on really well. Sienna had her heart broken by Jude, but she was young and it was the first time she'd fallen in love. What people don't realise is that they always remained close, so who knows where this will lead to next.

"They're desperate to keep their hook-ups secret because their break-up was so public. They don't want any potential reconciliation all over the papers, especially with Jude having just fathered a child with another woman."

It was also claimed that the pair have enlisted the help of friend Johnny Lee Miller in order to protect their romance.

The insider added: "Johnny's great at throwing the paparazzi off the scent. He'll walk down the street with Sienna to where Jude's staying just round the corner."

A spokesperson for Law, who is currently starring in the Broadway production of Hamlet, confirmed that the two did recently meet up.
