AceShowbiz - Britney Spears made use of her Instagram account to call out paparazzi. In a new Instagram post, the "Toxic" singer called out the paparazzi for taking photos of her entering and leaving a gas station restroom in Los Angeles.

Recalling her "s**tty day," Britney wrote, "I had a s**tty day yesterday!!! Paps took pics of me coming out of a public bathroom," alongside a video set to Madonna's "Vogue" featuring herself modelling a variety of outfits in front of her Christmas tree. "I mean how embarrassing is that ????"

"So right when I got home I had a PFC... it means 'party for confidence' and I swear if you have confidence struggles or low self esteem and need to practice walking with your head held high and kinda hunched over... you must try it !!!!" Britney added. As for what PFC entailed, the 39-year-old pop star explained that it included putting "some heels on and a dress," putting "sparkles on your body," putting "on Nicki Minaj and play it LOUD," and keeping "your head held high no matter what and just shake what ya mama gave ya !!!"

"I mean I've NEVER DONE THIS BEFORE EVER," she added. "Except for last night of course."

This is not the first time for Britney to express frustration regarding paparazzi invading her personal space. Back in June, the "Toxic" artist said it was "really not fun" to have photographers follow her to Hawaii during her vacation with now-fiance Sam Asghari.

"It's pretty hard going anywhere cause these silly faces keep popping up to take my picture," she wrote on her Instagram. "But not only do they take my picture … they distort my body and mess with the image and it's embarrassing !!!!!"

She went on to say, "I know my body is not perfect but I definitely do NOT look like how they portray me. It's rude and it's mean so paps kindly F**K YOU AND F**K OFF !!!!"
