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."
