Ryan Phillippe and longtime girlfriend Paulina Slagter are apparently getting married! The "Cruel Intentions" actor and his girlfriend are reportedly engaged after Phillippe proposed to the 24-year-old Stanford Law School student over the Christmas holidays, according to Page Six.

The newly engaged couple were spotted having lunch at Seaspice in Miami on Sunday, where Slagter was seen showing off her engagement ring. Phillippe and his fiancée, who started dating four years ago, are planning to ring in the new year at the Five Star New Year's Eve party on Watson Island.

Phillippe, 41, was previously married to Reese Witherspoon for nine years and has two children with the "Legally Blonde" actress - a 16-year-old daughter, Ava, and a 12-year-old son, Deacon. The actor also has a 4-year-old daughter, Kai, with ex-girlfriend Alexis Knapp, according to People.

"She's awesome," Phillippe told Howard Stern in April this year, according to E!. "When people see her they have these judgments because she could be a model but she's about to graduate Stanford Law. 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."
