'Mean Girl' Lacey Chabert Secretly Ties The Knot: See Her Dress

Last week, the actress went from Mean Girl to married woman.

It looks like Gretchen Weiners finally had her moment.

From "Mean Girl" to married woman: Actress Lacey Chabert announced on Friday (January 3) that she had married her boyfriend over the holidays.

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

Chabert tied the knot in late December, revealing the life change only today. She posted a picture of herself in her gown hugging her maid of honor, sister Crissy.

"Big Bang Theory" star Kaley Cuoco, a New Year's Eve bride herself, was reportedly in attendance, as was "The Bachelorette" alum Ali Fedotowsky.

Chabert had not previously announced an engagement, nor is her beau's name public knowledge. (We're mostly curious about whether his hair looks sexy pushed back.)

Nice work on the surprise marriage, Chabert, but you wore your hair in a ponytail more than once this week. You can't sit with us!
