Former Gilmore Girl Alexis Bledel and Mad Men star Vincent Kartheiser are engaged.
The Mad Men stars have announced plans to tie the knot after around one year of dating.
The co-stars have enjoyed a romance on screen as well as in real life; Alexis played the mentally imbalanced mistress to Vincent's advertising executive character Pete Campbell in the US show.
"They couldn't be happier," a friend said of the actress told Us Weekly magazine.
Her representative also confirmed the news to the publication.
Another source spoke about the piece of jewellery Kartheiser, 33, gave his 31-year-old partner.
Explaining that the big moment came some time ago, Bledel was apparently presented with an oversized piece for her hand which she hasn't been keeping a secret.
"Vincent proposed a few weeks ago," the insider revealed. "She's been wearing her ring. It's huge!"
News of the pair's relationship broke last June, after they had been "dating for a few months".
Kartheiser has dated actress Rachael Leigh Cook in the past while Bledel is no stranger to being romanced by a co-star.
The former Gilmore Girls actress was with her on-screen love interest Milo Ventimiglia for more than three years.
It will be the first marriage for both, who attended the wedding of her Sisterhood of the Traveling Pants co-star Amber Tamblyn when she married David Cross in October.
"They are so cute together!" another source added about the happy couple.
