Britney Spears was pretty active on Instagram on Monday night.

She posted a clip that featured her singing.

The phone was pointed at the ceiling and Britney was not seen in the video.

On Tuesday, Britney claimed she was “mortified” that she posted the video.

“I posted the wrong video of me singing yesterday,” Britney wrote.

“Once I did, I tried to play it off with the caption,” she added.

“I was in the studio messing around and I accidentally posted that version !!!” she wrote.

Many fans wondered why Britney didn’t just delete it if she posted it by accident.
