Vincent Kartheiser told On the Red Carpet it was just random circumstance that led the news of his engagement to Alexis Bledel to come out the day before the big premiere for Mad Men Season 6.

Vincent didn't really want to talk about the engagement on the red carpet, preferring to stick to Mad Men subjects, but he did confirm he's gonna get hitched, adding, "I'm a very lucky man." He also said he's having trouble remembering the term change. "I keep saying girlfriend, and them I'm like, 'I mean my fiancee! Yeah, I do a lot of that." He'll have to change it to "wife" soon!

Vincent and Alexis co-starred on Mad Men Season 5, when their characters had an affair. "They are such a yin and yang," Elisabeth Moss (Peggy) told People. "I've known Vinny for 12 years and Alexis is just the sweetest. I've never seen Vincent like this. It is really cool." Jessica Paré (Megan Draper) added, "It was purely comedic but he was giving [Elisabeth] and I a facetious rendition of his planned proposal. We were like, 'Great! Lets do this one without cursing and without yelling!'"
