According to Matt, the previous relationship was pretty good.
The couple’s love chemistry in reel life was good; both had a good mutual understanding.
Bledel and Kartheiser first met on the set of Mad Men , when Bledel appeared in a guest-starring role in 2012 in the show's fifth season.
Bledel played the mistress of Kartheiser's character, Pete Campbell, in a three-episode arc, and the rest is history.
And they've been acting since before they can remember, which makes for a very special personality.
