Ryan Phillippe is ready to walk down the aisle again.

The 41-year-old actor proposed to girlfriend Paulina Slagter, a Stanford Law School student, over the holidays, an insider told Page Six.

Phillippe told Howard Stern earlier this year that his relationship with twenty-something Slagter was serious, and that he was “not opposed” to getting married again. The duo started dating a few years ago.

Phillippe was previously married to Reese Witherspoon from 1999 to 2008. They share a 16-year-old daughter named Ava and a 12-year-old son named Deacon. Witherspoon, 39, married agent Jim Toth in 2011.
