January Jones is not letting an online hater get the best of her.

On Monday, The Mad Men star, 44, shared a video of herself of herself singing her own rendition of Celine Dion's "My Heart Will Go On" while wearing no makeup and an oversized stripped sweater. She also showed off her new haircut in the short clip.

"We got a vocoder, thinking about a career pivot," she captioned the video.

Commenters were quick to support her musical skills, but one Instagram user criticized her casual look, to which Jones had the perfect clap back.

"Wow, is that what she looks like without makeup. Yikes," the critic wrote in the comment section, to which Jones replied, "Oh it gets worse, I also haven't brushed my teeth yet and I have a stye."

Earlier this month, the Emmy nominated actress debuted her epic, childhood-inspired bowl cut — complementing the look with a chic red lip — in an Instagram video.
