swings no more.
to Canadian real estate agent Kyla Weber, Vaughn, 39, says he wants to start a family and settle down.
The funny guy even says he's ready for diaper duty. "It's the first time that I really want to have kids," he told PEOPLE while promoting his new comedy Couples Retreat
"I've been very fortunate in my career, and my life has been about that for so long that you get bored of it. You're ready for your life to be about other people and other things," Vaughn said.
While filming the movie – costarring his longtime pal Jon Favreau and directed by another friend, Peter Billingsley – Vaughn spent time in exotic Bora Bora with his soon-to-be wife and members of his family. "We had a lot of fun, which was good, and my sister was there and my nephew was there," he says.
And his buddies have given their approval.
"I'm very happy for Vince. He's marrying an amazing girl," says Billingsley, the former child star of A Christmas Story
. "It's a natural cycle of life that we all go in."
But Billingsley admits one thing is dramatically different from the days when Vaughn and Favreau – who starred in the 1996 Swingers
– were making the Hollywood scene.
"The parties are a lot different than they used to be – that's for sure!" Billingsley says. "I still come with the point of view to have a great time, but it's kids and strollers and babies and clowns."
