Owain Yeoman Marries Gigi Yallouz

It’s all about weddings for Owain Yeoman these days!

The Mentalist star tells PEOPLE he tied the knot with his fiancée, jewelry designer Gigi Yallouz, on Sept. 7 at a private estate in Malibu, Calif.

But wait, there’s more.

The Welsh actor will say ‘I do’ again on the CBS drama’s Oct. 13 episode when his character, Wayne Rigsby, weds his colleague Grace Van Pelt (Amanda Righetti).

“There I was with Gigi on one side and Amanda on the other,” says Yeoman, 35, laughing about taking part in “two weddings in the span of two weeks.”

Yeoman s French bulldog, Cash, collaborated with his master’s engagement to Yallouz last October. He also walked his best friend down the aisle at the outdoor wedding ceremony, attended by about 100 guests.

“I was completely upstaged,” jokes Yeoman, adding that Cash did have to stay home while the couple honeymooned in Bora Bora.

On a more serious note, Yeoman tells PEOPLE he’s just happy to finally be a married man.

“Gigi is my perfect partner. She’s my best friend. She’s the most fun of anyone I know and she’s also the kindest and most tolerant person,” he says. “I work in a business of extremes, so when you are with someone who is very calm and logical, it’s a great kind of balance to have. She really is my soulmate.”
