The 33- year-old admits that he had suicidal thoughts after his marriage came to an end after seven years.
"After the divorce, I was a physical wreck. I wanted to die, I was ready to kill myself. I was not taking care of myself at all. I would wake up and cry and vomit," usmagazine.com quoted him, as telling Man About Town magazine.
He also revealed that having kids has made him a better actor, for he can cry faster on cue.
"Now, it's f---king easy. When I was younger, I didn't have enough to cry about. But since I've had kids, I feel my work has become better, because my life is fuller and more complicated, and I've experienced so many highs and lows," he said.
Phillippe and Witherspoon share custody of their kids Ava, 8 and Deacon,4.
Phillippe will return to big screen in the March drama Stop Loss — which again teams him with former flame Abbie Cornish. (ANI)
