Kate Winslet shows off new boyfriend

Kate Winslet has gone public with her new boyfriend by treading the red carpet for the first time as a couple.

The Oscar-winning actress announced in March that she had separated from her husband of seven years Sam Mendes and she was subsequently linked to British model Louis Dowler.

Rumors of a blossoming new romance were fueled when Winslet was pictured walking hand-in-hand with Dowler in London over the summer and now she appears to have confirmed the relationship with a red carpet outing to a Vanity Fair photography exhibition in Spain on Monday.

Dowler was pictured posing with his arms wrapped around the actress' waist as they attended the Todo o Nada event in Madrid, and Winslet was also photographed lovingly placing an arm around the model's neck.
