She made the revelation in a long Instagram post where she also shared her experience with the popular treatment and even described it as 'horrific'.

On her Instagram page, which is followed by 42.1 million netizens, the singer wrote: "OK … I have a big forehead and I seriously need bangs but I feel like I can’t see sometimes with bangs !!! I’m sharing this because it actually really does work."

"Too many times, these so-called “best doctors” do amazing Botox. Never again in Los Angeles. My first time, I just did lips ? in New York City. WAY different than LA … so subtle, it was an adorable pout !!!" she said.

"The place had all hardwood floors and was raw. For probably 10 to 15 years, I haven’t had mine done right, and what’s with the times when one eyebrow is up and one is down ?? I can’t even be seen for 2 weeks," she said.

"But not in real life when one eye is black and blue and way higher than the other ?. I cried and then I’m like, when is this gonna go away?" she said.

"F*** BOTOX, it is horrific !!! Sio is unbelievable," she said.

In the world of her works, Spears recently collaborated with Will.i.am for “Mind Your Business” last month.
