Who Is Ryan Phillipe's Girlfriend, Paulina Slagter?

Not much is known about Paulina Slagter, 20, the girl with whom actor Ryan Phillipe, 38, has been spotted at various locations across Los Angeles, but the leggy blonde is warming up to the spotlight.

Having recently completed her third year of a Political Science and History degree at Los Angeles's Loyola Marymount University, Slagter has been linked with Phillipe since last December. Most recently, she accompanied Phillipe (via a discreet backdoor entrance) to Wednesday's STK L.A. Anniversary party in West Hollywood.

"Ryan drove in through the garage to avoid paparazzi, and he was brought into the restaurant through the kitchen," a source told People. "He and Paulina were very cute and held hands at their private table, tucked away from the rest of the crowd."

Slagter, who in addition to being a college student is also a model and actress (she had a bit part on HBO's Entourage when she was 15), has apparently gotten cozy with Phillipe's ever-growing family. Earlier this week, she went grocery shopping with Phillipe and his son, Deacon, 8, according to the Daily Mail. In addition to daughter Ava, 12, Deacon is one of Phillipe's two children with actress and ex-wife Reese Witherspoon. Phillipe has a third child, son Kailani, almost 1, with ex-girlfriend Alexis Knapp.
