While some ex-lovers find it difficult to remain friends, it seems Reese Witherspoon and Ryan Phillippe are very much a part of each others' lives.
The couple - who have two children together, Ava, ten, and Deacon, six - have remained friends since their divorce in 2006.
Such good friends, in fact, that they help each other through the ups and downs of their existing love lives.
"It's gotten to a place where we're great friends and great co-parents," actor Ryan tells a US radio show.
"After I had my break-up, she called, and after she did, I called."
Ryan had been dating Australian actress Abbie Cornish, while Reese, 34, was seeing Jake Gyllenhaal.
