sienna millerSienna Miller has been photographed kissing Balthazar Getty, just weeks after they denied they are romantically involved.

Sienna was first linked to the married Brothers & Sisters actor late last month but the pair denied that there was anything going on between them and that their romance had caused Balthazar’s wife to flee to Italy with the couple’s four children.

But photos have emerged of the couple together on a romantic break on the Amalfi coast in Italy, sunbathing topless together and kissing during a cruise on a yacht.

A source told the Sun: “They were all over each other for the whole afternoon.

“They had no qualms about showing the world they were together There was lots of kissing and cuddling.”

Sienna is said to have finished with boyfriend of a year Rhys Ifans to pursue her relationship with Balthazar after the couple were introduced by their Edge of Love/Brothers & Sisters co-star Matthew Rhys.

But just a month after being heartbroken over the split, Ifans told the People newspaper that he’s “well over” the Factory Girl actress: “F*** Sienna, I’m over it.

“Everyone thinks I am sad. I was, but I’m not anymore. I know people have been worried about me but there is no need, honestly. I’m fine.

“I’m having a great time. I won’t be going for anymore wrong ‘uns though.”
