Britney Spears responds after Ozzy Osbourne calls her dancing 'sad': 'Kindly f--- off'

Don't expect Britney Spears to dance to "Crazy Train" any time soon.

On Wednesday, the "Gimme More" singer clapped back at rocker Ozzy Osbourne and his family's comments about the dance videos she regularly posts on social media. She wrote in a lengthy, wide-ranging Instagram post (below) that she planned to "tell the Osbourne family who is the most boring family known to mankind to kindly f--- off!!!"

Spears objected to some things that were said on the July 16 episode of The Osbournes Podcast, in which the former Black Sabbath frontman said he was "fed up with seeing poor old Britney Spears [dancing]. Every f---ing day." He added, "You know, it's sad. Very, very sad."

Sharon, Kelly, and Jack Osbourne agreed.

"I feel so sorry for her," Kelly said.

Her brother Jack called the situation "very sad indeed."

Meanwhile, Sharon called her "a poor little thing."

Spears was not having any of it. Her post began with a question about whether fans had ever seen the Kate Beckinsale movie Serendipity, the 2001 romantic comedy with John Cusack. She went on to say that she adored Beckinsale and heard people were being "incredibly cruel" in saying the 50-year-old actress should share "more age appropriate content." (Beckinsale herself is great at responding to critics, as she did this week with a swimsuit that read, "I did not ask your opinion.")

Spears noted that "I hardly ever dance" and "I'm not poor at all!!!"

Though Spears will continue to dance regularly, she's said that she will "never return to the music industry, at least not the same way. She said that she has "written over 20 songs for other people" in the past two years, working as a ghostwriter.
