Britney Spears deleted her Instagram account amid a number of worrying posts and a public dispute over her ex-husband Kevin Federline’s memoir.

On Sunday, Nov. 2, Spears’ Instagram account was no longer available to view, and a message stated her “profile may have been removed.”

In recent weeks, fans expressed concern after Spears, 43, posted living room dancing videos but opted to turn off comments on posts. That had cryptic captions about her kids, Jayden James, 19, and Sean Preston, 20.

A video Spears shared to social media on Oct. 7 showed her with bruises on her arms and bandages wrapped around her hands and wrists. In the caption, Spears explained that she had fallen down stairs and wrote about her two sons traveling back to Hawaii. Where they reside with Federline, 47.

“My boys had to leave and go back to Maui,” she wrote, before opening up about why she shares her dancing clips. “This is the way I express myself and pray through art … father who art in heaven … I’m not here for concern or pity, I just want to be a good woman and be better … and I do have wonderful support, so have a brilliant day !!!”

She continued, “PsssI fell down the stairs at my friend’s house … it was horrible. It snaps out now and then, not sure if it’s broken but for now it’s snapped in !!! Thank u god.”

In a more recent Instagram post shared on Oct. 19, the pop superstar seemed to open up about spending four months in rehab in 2018 while under a 13-year conservatorship and the impact it’s had on her life. In the post, she claimed she said “brain damage happened to me.”

Spears posted a photo of herself riding a horse and compared her shoulder blades to “wings” in the caption. Before writing about the film Maleficent.

In Federline’s memoir, You Thought You Knew, he shared various claims about Spears, their marriage and her relationship with their sons.

Excerpts from shared by The New York Times, USA Today and E! Online feature claims about Spears’ behavior as a parent, allegations of cheating and an expression of imminent fear that “something bad” will happen to her.

On Oct. 15, Spears used X to call out Federline for “constantly gaslighting” her and defended her relationship with their sons

Spears also took aim at Federline’s press appearances, accusing him of “literally attacking” her “in his interviews.”

“Why is HE SO ANGRY,” she questioned, adding, “and what’s scary is he’s convincing. It literally blows my mind the moments he stops before he cries are you f—ing serious …”

A rep for Spears responded to Federline’s memoir and the allegations in a statement shared with PEOPLE on Oct. 14.

“With news from Kevin’s book breaking, once again he and others are profiting off her and sadly it comes after child support has ended with Kevin,” the statement reads. “All she cares about are her kids, Sean Preston and Jayden James, and their well-being during this sensationalism. She detailed her journey in her memoir.”
