What’s all the fuss about? Mean Girls star Lacey Chabert announced her first pregnancy with husband Dave Nehdar in an adorable Twitter post she shared with fans on Saturday, February 27 — featuring her tiny chihuahua pup, Kitty.

“Kitty doesn’t seem as excited about this as we are … I’m pregnant!!!!” she captioned the picture. “My husband and I are thrilled & so thankful.”

In the hilarious image, Kitty wears a pint-sized shirt with lettering on the back.

“My mom is having a baby & all I get is this silly shirt,” it reads. Chabert’s dog doesn’t look particularly amused as she gives the camera a side-eye in the photo.

Chabert, 33, tied the knot with Nehdar in December 2013 in a star-studded ceremony in Los Angeles.

Kaley Cuoco, her sister Briana Cuoco, 8 Simple Rules actress Amy Davidson and Bachelorette alum Ali Fedotowsky were all in attendance.

“I’m starting off 2014 as a Mrs!” the Party of Five alum wrote on Twitter at the time. “Over the holidays, my best friend & love of my life … we became husband & wife! #soblessed #love.”

Chabert currently stars on TV Land series Teachers.
