Alexis Bledel Engaged to 'Mad Men' Co-Star Vincent Kartheiser!

Alexis Bledel's Mad Men love affair with co-star Vincent Kartheiser has heated up off-screen. The couple, who have been dating since last summer, got engaged a few weeks ago. Her rep exclusively confirmed the bridal news to Us Weekly.

"They couldn't be happier," said a friend to the Gilmore Girls star. Another source revealed, "She's been wearing her ring. It's huge!"

Mixing business and pleasure usually means a break-up in Hollywood, but we are glad our dear old friend Rory is working it out.

Congrats to the lovely couple!
