Sienna Miller has been seen in an intimate embrace with married father-of-four Balthazar Getty while holidaying at the Italian Riviera.

The 26-year-old actress, who recently ended her relationship with Welsh boyfriend Rhys Ifans, first sparked rumours she was romancing the oil heir when the pair were spotted enjoying a series of dates in Los Angeles last month.

The new couple were seen giving each other affectionate hugs, loving strokes and romantic kisses as they frolicked on a beach in the popular idyllic paradise.

'Brothers and Sisters' star Getty is said to have joined Sienna on the sunny getaway after his wife Rosetta reportedly left their family home following the publication of images of her husband wining and dining Miller.

Sienna, who has insisted that her and Getty are "just friends", has been house hunting in Hollywood recently, as she allegedly feels uncomfortable in London after her break up with 'Notting Hill' actor Ifans, and her 33-year-old pal is helping her find the perfect property.

A source said in The Sun: "Balthazar has given her pointers on the most exclusive areas."

Miller met Getty through ex-boyfriend Matthew Rhys, who co-stars on the hit US drama.
