Anna Friel spotted kissing 'Breakfast at Tiffany's' co-star

London, Dec 7 (ANI): Brit actress Anna Friel was spotted locking lips with her 'Breakfast at Tiffany's' co-star during a night out.

Friel, 33, who is Harry Potter star David Thewlis' partner in real life, was seen sharing a ciggie with American actor Joseph Cross before she leant over to give him a lingering kiss.

The actress has been appearing opposite Cross, 23, in the West End stage adaptation of Truman Capote's 1958 novel, and the two have been sharing three nights out together in London last week alone.

The pair, who are performing at The Theatre Royal in Haymarket, hit three trendy bars on December 2 before snuggling up in plush restaurant The Wolesley.

They were out again on December 3 when they went to The Berkeley Square Christmas Ball with Thewlis, and they met up again on December 5 when they were seen kissing.

"They have a great chemistry on stage and are obviously close friends off it," the Sun quoted an onlooker as saying.

"But I was still surprised when I saw Anna plant him with a kiss on the lips," the onlooker added. (ANI)
