Former The Real Housewives of New York City star Kelly Bensimon has found love with Million Dollar Listing stud Ryan Serhant, Star magazine reports.

According to the tabloid, Kelly, 44, and Ryan, 28, are "really happy" together and met in December at a fundraiser for Hurricane Sandy.

"They were just friends, but since that event, things have been heating up!"
