Josh Hartnett has been seen out with a mystery blonde.
'The Black Dahlia' star - who has been romantically linked to Penelope Cruz - was spotted at New York's Snitch Bar last week with the beauty.
The sexy blonde showed off her stunning pins in a pair of thigh-high leather boots and turned the heads of most male revellers.
An onlooker told the New York Daily News newspaper: "She sat on his lap in thigh-high black boots and white shorts while he chain-smoked."
Hartnett has been a regular on the New York party circuit recently. Last week, he flashed his naked butt to fellow dancers at the Beatrice Inn nightclub. The 28-year-old star exposed his behind as he danced in low-slung jeans that slipped down to expose his manly buttocks.
A fellow reveller said: "One guest pointed out to Josh he was flashing a lot of skin, but he was perfectly relaxed and replied, 'It's cool, I never wear underwear.' He didn't seem to care that he was showing his bare behind."
Since splitting from Scarlett Johansson last November, Hartnett has been seen canoodling with Brazilian supermodel Gisele Bundchen and enjoying a romantic Caribbean holiday with actress Cruz. |
