Lauren Conrad's TV exes, Doug Reinhardt, 28, and Jason Wahler, 25, are both engaged to their girlfriends.
Reinhardt popped the question to Allie Lutz, 26, according to a post on her Twitter account.
"Cat's out of the bag," Lutz, who dated Reinhardt – a former Angels and Orioles baseball player – on and off since high school, wrote underneath a photo showing off her ring finger bling and being kissed by her fiancé. "#Engaged #bestfriend #highschoolsweetheart."
A rep for the Reinhardt family confirms the news to PEOPLE, adding, "They [got] engaged on a yacht Doug chartered for New Year's. Doug proposed on the yacht at St. Barts and afterwards arranged a lavish celebration while cruising around St. Barts and Anguilla."
Lutz is no stranger to The Hills cast. She feuded with Kristin Cavallari on the final season of the show while her pal dated Brody Jenner.

Aside from Conrad, 26, Reinhardt, known for his string of young Hollywood romances, has also courted Amanda Bynes, Paris Hilton and former Miss USA Rima Fakih.
Meanwhile, Conrad's first serious boyfriend Wahler proposed to his Fashion Institute of Design and Merchandising graduate girlfriend of a year-and-a-half, Ashley Slack, seven weeks ago, according to his Instagram.
"Love you babe!" Wahler, who was previously engaged to USC tennis player Katja Decker-Sadowski, wrote in a caption that accompanied a photo of Slack wearing her engagement ring.
Wahler, a former Celebrity Rehab patient, told PEOPLE in 2011 that he made amends with Conrad since becoming sober, and he has "a much clearer head."
Conrad, on the other hand, doesn't appear to have any engagement news of her own, but seems to be just fine in her relationship with William Tell.
