Back in April, Phillippe gushed over his gorgeous girlfriend during a sit-down with Howard Stern.

"She's awesome. When people see her they have these judgments because she could be a model, but she's about to graduate Stanford Law," he shared. "Also what's great about it -- as you get older certain issues become more important to you. I'm very involved in civil rights issues, and so to be with a woman who could actually make an impact in the legal realm -- that's a beautiful thing."

Phillippe was previously married to his Cruel Intentions co-star Reese Witherspoon from 1999 to 2007. The pair share two children -- 16-year-old daughter Ava and 12-year-old son Deacon. Phillippe is also father to a 4-year-old daughter, Kai, who he shares with ex-girlfriend Alexis Knapp.
