Lisa Rinna's daughter, Delilah Belle Hamlin, is reportedly dating Cully Smoller, the longtime assitant and friend of her fellow model Gigi Hadid.

According to a new report, the Real Housewives of Beverly Hills star’s oldest daughter with husband Harry Hamlin has been casually dating and "hooking up" with Cully Smoller.

Us Weekly shared the news on Feb. 13, revealing that the couple was first spotted enjoying an evening out in Los Angeles in September of last year. At the time, the outlet revealed, they were caught by photographers outside of On the Rox.

While Delilah Belle resided with her mother, sister Amelia Gray, and father, Harry Hamlin, up until recently, she relocated to New York City after signing a deal with IMG. Since then, she has been spotted out and about in the Big Apple as the Real Housewives of Beverly Hills star frequently speaks about missing her on social media.

Rinna also recently spoke on the show about her daughter's move to the East Coast.

“Just the thought of Delilah going to New York, I think it’s great, [but] she’s going to be there and I’m not going to get the door closing,” Rinna told her costar, Erika Girardi. “She doesn’t always know how to say no. I have every hope and faith but I’m a worrier. It’s going to be hard … I’m going to worry.”

During the eighth season, Rinna and Girardi were seen traveling to Tokyo with Delilah Bella and Amelia Gray.

Although Delilah Belle and Smoller have been seen publicly on a number of occasions, they don't appear to have confirmed their relationship quite yet. In fact, they seem to be keeping a very low profile and have yet to speak of each other on social media.

In addition to his working relationship with Hadid, Smoller also appears to be quite close friends with her younger sister, Bella, and frequently shares photos of the two women on his Instagram page.

The Hadid sisters' mom, Yolanda Hadid, appeared alongside Delilah Belle's mom on The Real Housewives of Beverly Hills for two seasons before quitting ahead of season 7 in 2016.
