It's a match made on "Mad Men."
"Mad Men" co-stars Alexis Bledel, 31, and Vincent Kartheiser, 33, are taking their onscreen passion offscreen. The two, who went public with their romance last October, are engaged, a representative for the actress confirmed to ABC News Radio.
On the juicy AMC drama, Bledel plays Beth Dawes, who seduces Kartheiser's character, Pete Campbell, into a steamy affair.
This will be the first marriage for both stars. Kartheiser previously dated actress Rachael Leigh Cook and Bledel dated her "Gilmore Girls" co-star Milo Ventimiglia for more than three years.
