Ryan Phillippe believes age was the the problem with his marriage to Reese Witherspoon.
"I think more of the problem was age, you know, when we got together so young," explained Phillippe, now 40, being sure to refer to Witherspoon as his ex. "I think it can create issues -- two people in this industry -- because there's so much noise that goes along with it."
The couple met at a mutual friend's birthday party, then costarred in 1999's "Cruel Intentions." They married in June 1999, while they were both in their 20s. Daughter Ava, now 15, arrived three months after they said "I do," and they later had a son, Deacon, now 11.
He and Witherspoon announced their separation in October 2006 amid cheating rumors and their divorce was finalized in the middle of 2008.
The "Wild" actress, 38, opened up about their high-profile split in a "60 Minutes" interview last December and blamed her career slump on their divorce.
"You know, you can't really be very creative when you feel like your brain is scrambled eggs," she said at the time. "I was just kind of floundering career-wise cause I wasn't making things I was passionate about, I was just kinda working. It was really clear the audiences weren't responding to anything I was putting out there."
Phillippe also told King that that he and his ex remain "very much" friends and are devoted to their kids.
Meanwhile, the "Damages" alum said his reputation as a Hollywood bad boy puzzles him.
"I'm a pretty regular dude," he said, adding: "I'm also a pretty dedicated dad and have multiple companies, so there's not a lot of time for me to be a Hollywood bad boy."
