Ryan Phillippe's ex-wife Reese Witherspoon has been supporting him through his split from Abbie Cornish.

The 35-year-old actor - who recently ended his four-year relationship with the Australian actress - insists he is still "great friends" with his former spouse, and also helped her after she ended her romance with Jake Gyllenhaal in December.

Ryan - who has daughter Ava, 10, and six-year-old son Deacon with Reese - said: "It's gotten to a place where we're great friends and great co-parents.

"After I had my break-up, she called, and after she did, I called."

Despite their closeness, Ryan insists he has never been intimate with Reese since they split in 2006 after seven years of marriage.

He said: "That's never happened."

Reese is now dating Hollywood agent Jim Toth and Ryan has given their romance his blessing.

He told Sirius XM DJ Howard Stern: "I trust her to make the right decisions around our children. I hope she feels the same way."

Despite the recent relationship changes in their parents' lives, the 'Cruel Intentions' star insists his children are unaffected by his romantic choices.

He added: "If the kids care about mom and dad, and if that's consistent and they feel protected that way, they don't really care so much about who the parent is dating. They just don't."

Ryan also quashed speculation Abbie had dumped him, insisting the decision was mutual and he is tired of being "s**t on" when his relationships end.

He added: "I've been dumped on in the press for relationship stuff since Reese and I divorced. I'm tired of getting s**t on. I don't feel like I deserve it. Things happen!"
