"I'm starting off 2014 as a Mrs! Over the holidays, my best friend & love of my life...we became husband & wife! #soblessed #love," she wrote.

The former "Party of Five" star, 31, also posted a snapshot on Instagram, posing in her wedding dress with her sister Crissy by her side.

We haven't seen the groom yet, but he's definitely a lucky man!

The brunette beauty wore a stunning lace beaded gown with a sweetheart neckline, pulling her hair back into a beautiful up 'do.

This wasn't Lacey's only wedding over the holidays!
