Singer Sia went under the knife and had liposuction to boost her confidence.

The "Unstoppable" singer admitted on X, formerly Twitter, that her own insecurities impacted her decision to get the procedure. 

Sia, who is known for hiding her face under massive wigs and bows, revealed in October that she had a facelift performed by her "good friend" Dr. Ben Talei.

"Had to take a medication that made me put on a lot of weight that I just can’t shift with exercise or thyroid meds so I went in for lipo today," she wrote to her fans on X. "Please know that I am so lucky to have the resources to change the way I look and that when you see me looking crazy foxy again that I want you to know it did not come from diet and exercise."

Two months ago, Sia praised her surgeon for giving her the confidence to show her face once again after she got a facelift, and presented him with an award during the 5th annual Daytime Beauty Awards.

The notoriously shy musician is known for wearing huge headpieces and wigs to hide her face while performing on stage and just recently began showing her face in public.

"When Sia showed up onstage, everybody got out of their seats and they lost their minds," Dr. Ben Talei told Fox News Digital.

"Like, it was a whole ‘nother world for some reason … they just love her. Everyone loves her. And she came onstage and said publicly, ‘Ben did my facelift,’ and she started complimenting me, and she's super, super happy with it."
