Bruce Willis was left red-faced during his 51st birthday party when his alleged supermodel girlfriend snubbed his advances for a kiss. The 16 Blocks star celebrated the special occasion, at New York's trendy G2 lounge on Saturday night, with rumoured lover Petra Nemcova and star friends Joaquin Phoenix, Eva Mendes and Clive Owen, among others.

Later in the evening, Willis was seen moving in for a birthday smooch with Petra, but the catwalk beauty - who the actor reportedly stood up at the US premiere of 'V For Vendetta' last week - spurned his efforts. An insider told New York Post newspaper: "She shied away from his kiss and then left alone. Petra is playing it safe."
