Alexis Bledel and Vincent Kartheiser got married...at the beginning of the summer, apparently.

According to E!, the couple tied the knot in a super-secret ceremony in California.

The actors have been engaged since March 2013 after meeting on the set of "Mad Men" -- Kartheiser stars as Pete Campbell and Bledel had a recurring role as Beth Dawes, a woman Pete had an affair with. They've kept their relationship on the DL, and they even waited until the fifth season of AMC series wrapped to start dating.

Congrats to the (already) married couple!
