The actress announced the happy news in a tweet on Friday (04Jan14).
Chabert wrote, "I'm starting off 2014 as a Mrs! Over the holidays, my best friend & love of my life... we became husband & wife!"
The actress' wedding guests included another newlywed, Kaley Cuoco, who married tennis ace Ryan Sweeting on New Year's Eve (31Dec13).
Chabert's Christmas and New Year's celebrations were marred by the death of her grandfather.
In a tweet on 28 December (13), she wrote, "What a week. Happiest & saddest of times. Ups & downs of life & mysterious way in which they always seem to collide will forever puzzle me."
And she later thanked fans for their kind words as she mourned the loss of her elderly relative, adding, "Thank you all so much for the sweet, comforting messages about my grandfather's passing. Your kindness touches my heart so very much."
