Lacey Chabert is married! The Mean Girls alum recently tied the knot with her longtime boyfriend, and announced the news via Twitter.

"I'm starting off 2014 as a Mrs!" the 31-year-old wrote on Friday, Jan. 4. "Over the holidays, my best friend & love of my life...we became husband & wife! #soblessed #love." Chabert has yet to reveal her groom, but a source tells Us Weekly his name is Dave Nehdar, and the two wed in Los Angeles.

Chabert said "I do" to her beau in front of famous pals Kaley Cuoco, her sister Briana Cuoco, 8 Simple Rules actress Amy Davidson and Bachelorette alum Ali Fedotowsky.

Shared in Instagram photos, the blushing new bride wore a stunning white lace gown for her special day. She also kept her brunette locks up in waves.

In a sad turn of events, however, Chabert's wedding was followed by the passing of her grandfather. "What a week. Happiest & saddest of times. Ups & downs of life & mysterious way in which they always seem to collide will forever puzzle me," she tweeted on Dec. 28.

"Thank you all so much for the sweet, comforting messages about my grandfather's passing. Your kindness touches my heart so very much xo," she added a day later.
