The reason for Ryan Phillippe and Reese Witherspoon's divorce is probably not unique.

Phillippe speaks honestly in his latest TV interview.

Ryan Phillippe has finally opened up about his marriage with ex-wife Reese Witherspoon, and why they divorced.

The celebrity duo married in 1999 just a couple of short years after meeting at Witherspoon’s 21st birthday party in March of 1997. They were young lovers and Phillippe, 40 told Larry King Now that this is what he believes caused their marriage to end.

“I think more of a problem was age. That we got together so young,” he told Larry King.

The actor and director dismissed the idea that their relationship didn’t last because they were both in the same industry, but admitted that Hollywood can put a strain on people’s relationships.

“I think it can create issues, two people in this industry because there’s so much noise that goes along with it,” he told the host.

Phillippe then opened up about that fact that he and Witherspoon, 38 are still very much friends, co-parenting their two children, 15-year-old Ava and 10-year-old Deacon.

Side note: we're in slight disbelief over this because we remember Phillippe as a young Hollywood heartthrob. But yep, here's Ava looking all grown up (and A LOT like her mum) today.

When asked if his daughter had started dating yet, Ryan said that she hadn't. Larry King asked if the doting dad was worried about it, and he said no.

"I don't think she'll suffer from fools," he told the host.

Wild star, Witherspoon, and Phillippe split in 2007 after being married for eight years. There were many rumours that Phillippe had an affair with Aussie actress, Abby Kornish. But Phillippe denied to Larry King that he was a bad boy.

Phillippe said he'd been with his current girlfriend, Paulina Slagter, for four years. "She's a civil rights lawyer so we have a lot in common with our interests..

Phillippe is also dad to 3-year-old daughter Kailana who he had with actress Alexis Knapp.

Do you think age is an issue when it come to marriage?
