It's a Mad Men romance gone official! Alexis Bledel is engaged to her former Mad Men co-star Vincent Kartheiser.
A rep for Alexis has confirmed the news to Us Weekly magazine, and a source dished, "They couldn't be happier... Vincent proposed a few weeks ago. She's been wearing her ring. It's huge!"
The couple started dating in 2012 after falling for each other on the set of the hit US TV show when Alexis joined the cast as Beth Dawes for a short stint.
A source previously said: "Vinnie basically fell in love with Alexis while she filmed a three-episode cameo. He was definitely smitten with her from the beginning."
And when she was working on Mad Men, Alexis had nothing but praise for Vincent.
She said at the time: "He's light and funny and has lots of energy on set. He keeps everybody energised as well."
This will be the first marriage for both - Alexis, 31, previously romanced her Gilmore Girls co-star Milo Ventimiglia, while Vincent was last linked to Rachael Leigh Cook.
