Jon Hamm isn't daddy material, apparently. There's a new report that says his girlfriend of 17 years, Jennifer Westfeldt, pulled the plug on their relationship because she was tired of waiting around for the Mad Men actor to change his mind about starting a family.

According to Star Magazine on Tuesday, a source close to the ex-couple says that Hamm and Westfeldt parted ways back in July and that their relationship simply "ran its course." What's more, Westfeldt also feels like she wasted her baby-making years trying to convince her boyfriend that they should have a child together.

The 45-year-old actress said back in 2012, "I never thought I'd be this age and not have kids."

Hamm famously told Playboy Magazine in the past, "We've seen enough of our friends, who shall obviously remain nameless, become parents, and sometimes it's hard not to think they shouldn't have had kids. I don't have a driving force to have a baby."

He added, "That said, I'm in a committed relationship, and if it ever came up, I'm not ruling anything out. There's a reason it hasn't been prioritized, because I don't think either of us has that pull."
