Marina Berlusconi Nipple Slip!!

The daughter of Italian President Silvio Berlusconi was somewhat worse for wear last night as she celebrated with her husband at a party in Monte Carlo.Clad in a figure-hugging dress that left little to the imagination, Marina Berlusconi swayed and staggered across the dancefloor at the opening of the Billionaire's Disco in the Monaco capital.

The 42-year-old at one point appeared to be held upright by her dancer husband Maurizio Vanadia.Unfortunately Ms Berlusconi's dress was not quite so supportive, her cleavage almost falling out of the gown's embellished bodice.The publishing guru, who was in town for the Monaco Grand Prix, holds several posts in her father's media empire, and was named by Forbes magazine two years ago as the 33rd most powerful woman in the world.

The mother-of-two is chairman of Italy's largest publishing house Mondatori, and deputy chairman of the family investment firm Fininvest.Mr Vanadia is the former first dancer of the La Scala opera house in Milan.The couple were celebrating the Monte Carlo launch of Italian playboy Flavio Briatore's Billionaire's Club, which has a sister outpost in Sardinia.
