The pair divorced in 2006 after seven years of marriage, and Witherspoon went on to date Gyllenhaal, while Phillippe began a relationship with Abbie Cornish. Witherspoon split from Gyllenhaal late last year (09) and has since been linked to talent agent Jim Toth.
Phillippe, who ended his romance with Cornish in February (10), has claimed that he always approves of Witherspoon's suitors, because he knows she will consider the best interests of their two children - Ava, 10, and Deacon, six.
"If the kids care about mum and dad, and if that's consistent and they feel protected that way, they don't they don't really care so much about who the parent is dating. They just don't... I trust her to make the right decisions around our children. I hope she feels the same way," the Daily Express quoted him as saying.
