Mad Men Star Ben Feldman Ties the Knot

Actor said "I Do" to his longtime girlfriend Saturday in Gaithersburg, Md.

Ben Feldman is a married man!

The 33-year-old Mad Men star said "I do" to his longtime girlfriend Michelle Mulitz at Smokey Glen Farm in Gaithersburg, Md. Saturday, E! News has confirmed.

Feldman and his ladylove tied the knot in a barn in front of about 350 guests, including Wolf Blitzer and Veep star Reid Scott.

Following their nuptials, the bride, groom and their guests enjoyed a night of dinner, catered by Occasions catering, and dancing in a separate pavilion, where they were serenaded by Tony winner Patina Miller and famed violinist Daniel Heifetz.

Guests also enjoyed the musical stylings of a blue grass band and a DJ.

"Michelle and I were so exited to share this beautiful day with our best friends and family in DC, and no amount of thunderstorms, police chases, government shut downs or self immolations could keep us from having the best party of our lives," Feldman told E! News.

The actor popped the question to Mulitz last December while they were out walking their dog.

Congrats!
