Mel Gibson worries about age gap between him and his girlfriend

Mel Gibson seems very happy with girlfriend Rosalind Ross but the actor says the 34 years age difference between them might cause a problem.

The 60-year-old star, who is expecting a baby with Ross, has a "trepidation" about their relationship as his girlfriend is only 26, reported Femalefirst.

"We dig each other. She is an adult and we dig each other. It might cause a problem and one has a trepidation about these things, but it's working out great.

"She is a really special person. I dig her. So there you go. That's it. What more can one ask?" he said.
