Sienna Miller Strips Down For Holiday With Married Boyfriend Balthazar

Sienna Miller has revealed the depth of her love for new boyfriend Balthazar Getty during a secret romantic break on the Amalfi Coast in Italy.

The actress looked relaxed and happy on board a boat with the American TV and film star as they shared a kiss in a very public display of affection.

These breath-taking pictures of the couple will devastate Sienna's former boyfriend, actor Rhys Ifans.

Despite Getty issuing a denial about their romance, the pair have been spending a lot of time together in recent months.

They were first spotted together around Los Angeles, having dinner at an Italian restaurant in Beverly Hills and meeting at the Chateau Marmont Hotel, the place where they first met in LA.

Getty, 33, is a married man and father of four children and heir to his family's oil fortune. He also appears to have a penchant for actresses, having previously dated Drew Barrymore and Milla Jovovich.

Sienna, 26, could be spending even more time with Getty as she is looking to buy a home in West Hollywood.
