Got married at the weekend.
Adler, 29, wed the 33-year-old actress on December 19 in an intimate ceremony at a private residence in the Hollywood Hills, reported Us magazine.
A source said, "The wedding was a very intimate affair of 75 of their closest friends and family."
Guests at the wedding included the star's former "Glee" co-star Darren Criss, and Adi Shankar, his producer on "Gods & Secrets".
