RadarOnline.com can confirm that Mario Singer has been happily playing house with his former mistress, Kasey Dexter, in Florida. And Dexter hasn't been shy about showing him off on her private social media accounts!
Dexter, 35, was involved in an on-again-off-again relationship with Mario, 64, while he was still married to Ramona, 60.
The couple's divorce was extremely bitter, but they reunited just last week for their daughter Avery's college graduation.
A former personal trainer, Dexter previously tried to woo Million Dollar Listing: NY star Ryan Serhant.
