Hayden Panettiere showed off her super-toned figure in a short tight dress last night. 

The Heroes star braced the cold weather in a lacy outfit that left little to the imagination.

The young actress - who recently had a new tattoo that reads 'to live' in Italian etched on her back - was at a party in Beverly Hills to celebrate the launch of BlackBerry Bold.

Desperate Housewives star Eva Longoria also attended.
