Harry Hamlin and Lisa Rinna Make Extremely Rare Red Carpet Appearance with His Son Dimitri

Harry Hamlin is hitting the red carpet with his wife and son!

On Thursday, Dec. 5, the actor and author, 73, was snapped at the Season 2 premiere of Anne Rice's Mayfair Witches in Los Angeles as he was joined by wife Lisa Rinna and son Dimitri Hamlin, whom he shares with actress Ursula Andress.

Posing for pictures at The Masonic Lodge at the Hollywood Forever Cemetery, Hamlin, who plays the role of Cortland Mayfair in the series, wrapped his arm around his wife 61, as she stood in between him and her stepson, 44.

Rinna dressed in a red asymmetric Balenciaga dress as she supported her husband during the evening, while Harry and Dimitri matched in black blazers.

It was a very rare red carpet appearance for the trio, who were last photographed at an event together in 2006 when they attended the launch of Roberto Cavalli Vodka.

Hamlin welcomed Dimitri with Andress, 88, in 1980. The former couple met while working on the movie Clash of the Titans and split in 1983.

Back in 2020, Rinna — who shares daughters Delilah Belle, 26,  Amelia Gray, 23, with Hamlin — spoke about her husband’s past relationship on an episode of The Real Housewives of Beverly Hills.

Speaking to her former costars Denise Richards, Sutton Stracke and Garcelle Beauvais about her admiration for the architecture during their trip to Rome, Rinna revealed her Los Angeles home with Hamlin "looks a little bit like this because Harry lived here for three years and he loves this."

"He was with Ursula Andress at the time and they had a child, she lived here," she explained. "They were doing Clash of the Titans together."

Andress was "the movie star that you would imagine" Rinna said in a confessional, before telling her cast mates that Andress made a move on Harry while they were filming in Europe.

"He said she called him and said, 'Harry, come to my room.' And so he did, at 28 years old, he went in and she got pregnant that night," Rinna said. "And that was that, at 44. First time."

Andress previously opened up to PEOPLE about her relationship with Harry after welcoming Dimitri.

"I was always very possessive," she said, adding that, "for Harry, his career is the main thing."

"Love affairs and husbands can end, but a child is forever. Dimitri is my love now," she continued.

Following his split from Andress in 1983, Hamlin went on to marry Laura Johnson from 1985 to 1989, as well as Nicollette Sheridan from 1991 to 1992. 

He then married Rinna in 1997.
