Doja Cat has undergone surgery on her infected tonsils.

The Kiss Me More singer explained to her Twitter followers that she was on antibiotics to treat her infected tonsils when she attended the Billboard Music Awards (BBMAs) on Sunday but the situation got worse and she had to undergo surgery to remove "a nasty a*s growth" from her left tonsil.

"Dr. just had to cut into my left tonsil. i had an abscess in it. my whole throat is f**ked so i might have some bad news for yall coming soon (sic)," she tweeted on Thursday. "So my tonsils got infected before bbmas and i was taking f**kin antibiotics but forgot that i was taking them and then i drank wine and was vaping all day long and then i started getting a nasty a*s growth on my tonsil so they had to do surgery on it today... i cried and it hurt a lot but im ok (sic)."

The 26-year-old, who won four awards at the BBMAs, told one follower that she was going to "try and get em removed" soon.

Doja confessed to her followers that she was struggling to go "cold turkey" and abstain from using her vape despite her sore throat.

"Im too scared to hit it cuz my throat hurts so bad. i cried for hours. its not worth it (sic)," she explained. "Then its like imagine all that wierd poisonous s**t in the vape seeping into the completely open wound in my throat like f**k that (sic).

"I'm addicted but I'm not weak. I was literally staring at my vape today that normally i'd hit a thousand times a day and hit it two times instead. I'ma try to go cold turkey for now but hopefully my brain doesn't need it at all by then."
