PARIS HILTON's ex-boyfriend DOUG REINHARDT is engaged to wed his high school sweetheart.
The former The Hills star proposed to Allie Lutz over the holiday season and she announced the happy news to fans via her Instagram.com blog on Sunday (06Jan13).
Lutz showed off her large sparkler in a cute image of the couple, alongside the caption, "Cat's out of the bag".
The pair is currently on vacation in Anguilla.
Reinhardt split from hotel heiress Hilton in 2010 after dating her on and off for less than a year. He also previously dated his The Hills co-star Lauren Conrad and briefly romanced former Miss USA Rima Fakih.
