Jack Nicholson

Jack Nicholson is a notorious ladies' man so it's no surprise that he was still fathering children into his 50s. His younger son, lookalike Raymond, was born when Jack was 54, two years after his daughter Lorraine.

He has five children in all and now that Raymond is grown up, the star recently revealed the trick to being an older dad. 'I want to be inspirational, or some kind of good influence on them without overburdening them,' he said.
