Saturday, April 28, was a good day for a white wedding—and an even better day for a reunion of The Office

Brian Baumgartner, who played Kevin Malone in the NBC show, married his girlfriend Celeste Ackleson this weekend in front of many of his fellow cast members.

Baumgartner, 41, said "I do" in the backyard of his Los Angeles home. His new wife, 32, stunned in a strapless white gown with lace details and a glittering tiara headpiece, while he wore a gray suit with a dark tie. 

Alums from The Office who were in attendance included Angela Kinsey, Jenna Fischer, Oscar Nunez, and John Krasinski with his wife Emily Blunt, who gave birth to the couple's first child Hazel in February. 

In the year since the May 2013 wrap of The Office, Baumgartner has landed bit roles in both Hot in Cleveland and Mike & Molly
