Mel Gibson, 59, Steps Out With 24-Year-Old Girlfriend — Plus More Star Couples With Significant Age Differences!

Mel Gibson may be gearing up to turn 60 next year, but the actor has successfully snagged himself a much-younger girlfriend (and we mean MUCH younger).

The 59-year-old was spotted strolling with 24-year-old Rosalind Ross in Sydney on Sunday when he reportedly had an altercation with a female photographer.

Mel's rep has since denied that he pushed and spat on the woman or called her a "dog" and a "c–t," but given his past incidents with the paparazzi, we're not surprised that the controversial Oscar winner was involved in another spat.
