The Hills's Doug Reinhardt and Allie Taylor Lutz Are Engaged! (PHOTO)

Baseball player and, well, overall player Doug Reinhardt has dated plenty of starlets over the years, but he found The One much closer to home.

Doug is now engaged to Allie Lutz, and she tweeted the news, writing, "Cat's out of the bag... ❤ 💎#engaged #bestfriend #highschoolsweetheart @ anguilla." She linked to a photo of Doug giving her a kiss as she showed off her engagement ring. The two are vacationing in Anguilla.

Doug, 28, dated The Hills's Lauren Conrad in 2008, then dated Amanda Bynes and Paris Hilton. Back in 2009, Paris talked to E! about being in love with Doug, saying, "He's going to be my husband." Guess not! Now he's Allie's future husband. According to Us Weekly, Allie is 26 and a graduate of the University of Southern California, and it sounds like she and Doug have been off-and-on for many years — apparently since high school.

Congrats to the happy couple!
