After spending time with German artist Niclas Castello, 46, in Saint Tropez last month, the 53-year-old Real Housewives of New York City alum returned home, where she shared a photo of Peter with her two dogs, Biggy and Smallz, on her Instagram Story.

“POV: Your ex husband comes over for a beach walk,” she captioned the August 4 photo, which included Peter’s tag.

Following the sharing of the post, Bravo and Cocktails on Instagram shared a message they received from one of their followers about Peter.

“I met him in Vegas in like 2010 and 2011 and partied with him. He’s actually so much fun. Typical LA guy and couldn’t imagine them together. But he was so nice to my friends and I!” the insider’s message read.

Meanwhile, in the caption of the post, Bravo and Cocktails wrote, “Bethenny was married to him before Jason, briefly in her early/mid 20s I believe … Lots of you saying he’s a party guy from LA lol.”

Bethenny’s reunion with Peter comes just days after the former RHONY cast member was spotted with Niclas and her daughter, 14-year-old Bryn Casey Hoppy, on the beach in Saint Tropez and months after she split from Paul Bernon, 45.

While Bethenny didn’t immediately confirm reports of her and Paul’s breakup, she opened up about the split on her podcast last month.

“Yes, I went through a breakup. It was something that I kept to myself. It was something that I mourned on my own and I did therapy and I did the work and I just didn’t feel like it needed to be shared. It was a breakup that I wanted to process alone,” Bethenny shared on Just B With Bethenny.
