Nicole Scherzinger sent her fans into a meltdown on Tuesday after she posted a picture to Instagram showing her lips looking rather plump.

"Guess who came out to play! The #london sun! #sunkissed," she captioned the selfie that shows her fully done up.

Few people were noticing her luscious hair, her flawless skin or the winter sun, for that matter. Everyone, it seemed, could only look at her plump pout.

One of her nearly 3 million followers wrote, "What have you done to your gorgeous lips?"

Another said, "Ur so pretty pls slow down on the fillers." Another fan said, "Those lips! WHAT?! WOW."

Some people liked her big lips.

"Loving the pout babe ur stunning and a inspiration to many women xx," one person said, while one woman asked her what particular shade she used because she "loving it."

Many people simply wrote things like "lips" or used mouth emojis to comment.

In an advertorial posted to her Instagram a day before, she made no mention of her lips, but did mention her beauty regimen.

"My beauty secret is out! Ever since I started to take Vitabiotics Perfectil, I feel like my skin and hair are more radiant than ever! Make sure to try this daily dose of vitamins!," she said.

In late August, she again got a little lippy when she posted a selfie to Instagram of her lipstick-heavy pout to celebrate the new season of "X-Factor," where she's a judge.

"Is that your normal face?" someone asked at the time.

Kylie Jenner would be proud.
