Jon Hamm is not interested in becoming a father anytime soon.

The 40-year-old actor and his partner Jennifer Westfeldt have been together since 1997.

The couple is going strong after spending more than a decade together, but children are not on the cards.

Jon believes that his busy schedule is full enough without having kids of his own to tend to.

"I have a lot of friends with kids and a lot of family members with kids," Jon told E! Online at Bovet 1822's Hollywood Domino Gala & Tournament. "I'm like a six time uncle. I have enough kids in my life."

The couple has recently been working together on upcoming movie Friends with Kids. Jon is elated that he and Jennifer get along so well professionally.

"It's a fun ensemble romantic comedy, it's a little edgier than most," Jon told BBC Radio 1. "We've been together going on 15 years. It's great, it's fun making a movie is hard work, especially when you don't have a studio behind you. It's a lot more than just a day."

Friends with Kids will be released in the US on March 9.
