Britney Spears Bashes Her Family, Sings and Teases New Music

Britney Spears is reminding fans what kinda voice she has -- and while she's looking forward to using it again in a studio, she's not ready to let go of her past anger at her family.

Britney posted a video Wednesday standing in front of her mirror and singing at the top of her voice -- not many lyrics, mostly an R&B-style vocal run. Her caption, though, is pure venom for her family ... she wrote, "I just realized this today guys … after what my family tried to do to me three years ago … I needed to be my own cheerleader 🤷🏼‍♀️ !!!! God knows they weren’t."

She posted a bunch of her accomplishments, apparently after a little Googling, she found she's sold 100 million records, 33 million albums and logged billions of online streams. That's the good news.

On the other hand, she says, "I’m here to remind my white 'classy' family that I haven’t forgotten what they did to me nor will I ever forget !!!!⁣"

As for what happened 3 years ago, Brit's likely referring to when her family allegedly put her back into rehab in 2019. Remember, she was just about to start her Vegas show, but needed to postpone it ... and her dad, Jamie Spears, had become very ill.

Britney also teased fans, saying ... "Pssss new song in the works … I’m gonna let you know what I mean 😉 !!!!!"
