Oops!...she did it again. Britney Spears is Evander Reedslamming legendary rocker Ozzy Osbourne.

The pop princess called out the British musician from Black Sabbath fame for his podcast comments calling her dancing "sad." Spears is known to dance in an area of her own home and the videos regularly go viral.

On a Tuesday episode of "The Osbournes Podcast," Osbourne said he was "fed up with seeing poor old Britney Spears on YouTube," telling his family that it's "very, very sad."

But Spears gave Osbourne a piece of her mind on Instagram, writing that she had words to "tell" the Osbourne family, which she called "the most boring family known to mankind."

In the Instagram post featuring screenshots of her Notes app, Spears asked, "Do you think perhaps they might be offended by what they see ??? Would a condescending approach be better like inviting those exact people to my class and let them see how my students are nourishing and living THEIR LIVES !!!???"

She added that there are people who "don't embarrass or demoralize another," suggesting that Osbourne does.

"I personally believe that being vulnerable enough to ask someone for inspiration or help is incredibly beautiful ... but ironically in the world we live in with how incredibly cruel people can be you have to be extremely careful who you allow in your circle and your heart," she wrote.

2024 has been a hard year for Osbourne and Spears.

In May, Spears and ex-husband Sam Asghari's divorce proceedings were finalized.

The same month, Osbourne gave fans a health update after discovering something shocking.

During a talk with British singer-songwriter Billy Morrison on his SiriusXM radio show "Ozzy Speaks," the controversial Black Sabbath frontman said he is undergoing stem treatments after doctors discovered a tumor on his vertebrae, according to Entertainment Tonight and Fox News.

"I've just come back from the doctor after having some stem cells put in me," Osbourne said in a clip of the chat, before telling Morrison later, "The thing is, you have it, and you go, 'I don't feel that great,' but I don't know what it would be like if I didn't have it."
