Days earlier, Phillippe and the law student took a break from getting tan to party at Miami's Wall nightclub on June 7. According to an eyewitness, the lovebirds sipped on Patron and kept it moving on the dance floor.
Phillippe began dating Slagter in December 2011 and has already introduced her to ex-wife Reese Witherspoon, 38, as well as his kids Deacon, 10, and daughter Ava, 14. The Damages actor welcomed daughter Kailani with Pitch Perfect's Alexis Knapp in July 2011. Witherspoon wed CAA agent Jim Toth back in 2011; the couple are parents to 21-month-old son Tennessee.
