Los Angeles: ‘Mad Men’ co-stars Alexis Bledel and Vincent Kartheiser confirmed that they share a romantic relationship and are getting engaged.
"The pair clearly have history going back a long way, so it looks like a rather lovely case of good friends becoming partners," contactmusic.com quoted a source as saying.
"Kartheiser proposed a few weeks ago. She`s been wearing her ring. It`s huge," the source added.
Kartheiser has previously dated actress Rachael Leigh Cook, whereas Bledel dated Milo Ventimiglia, who she was with for more than three years.
