When Peter met Beth! Vincent Kartheiser and Alexis Bledel have stayed extremely mum about their relationship since first meeting on set of Mad Men in 2012, but alas, Kartheiser has finally opened up (a little!) about his now-fiancee and how they only started dating after Season 5 wrapped.
"We were completely professional. We never saw each other out," the 34-year-old actor told Vulture. "We never—it was nothing, it was just work." (Kartheiser has played advertising-accounts executive Peter Campbell on the AMC series since its debut in 2007. The Gilmore Girls alum, 32, came on board in 2012 as Beth Dawes, who ultimately had an affair with Campbell.)
The Minnesota native may have never saw it coming, but according to costar Jon Hamm, the chemistry was obvious to others on set. "I did know he liked her from a very early point," he said of the courtship. "I was a supporter of that union."
"Honestly, they're a really good match," creator Matthew Weiner added. "They're both very down to earth, with a sense of responsibility and strong family ties. And they've been acting since before they can remember, which makes for a very special personality. It's not just that I thought they would look cute together."
He continued: "Even with all of Alexis's amazing qualities, I think that if she had not been such a good actress, he would not have been interested."
Us exclusively broke news back in March 2013 that the costars got engaged after dating for a few months. "She's been wearing her ring. It's huge!" a pal of the twosome told Us at the time. "They are so cute together!"
