Singer Britney Spears said she cried for weeks over a television documentary that examined her rise to fame as a teenager, the ensuing media scrutiny and her widely publicised breakdown.
In an Instagram post, the singer, 39, said she didn't watch the whole of Framing Britney Spears.
"But from what I did see of it I was embarrassed by the light they put me in ... I cried for two weeks and, well, I still cry sometimes," she wrote late on Monday in the post, accompanied by a video of her dancing to Crazy by Aerosmith.
The documentary, which also brought renewed attention to a long-running battle with her father over control of her financial affairs, was released last month.
Spears, who shot to fame in 1998 with the hit Baby One More Time, is seeking to replace her father, Jamie Spears, as her conservator.
He was appointed to the role in 2008 after she was hospitalised for psychiatric treatment.
Her fans have shown their support on social media under the hashtags #WereSorryBritney and #FreeBritney.
"I have been exposed my whole life performing in front of people. It takes a lot of strength to trust the universe with your real vulnerability cause I've always been so judged ... and embarrassed by the media ... and I still am 'til this day," Spears wrote.
"As the world keeps on turning and life goes on we still remain so fragile and sensitive as people ... I'm not here to be perfect ... perfect is boring ... I'm here to pass on kindness."
There was so much material for Framing Britney Spears, that the team behind it has even suggested a follow-up could be in the works.
"There was so much we had to leave on the cutting room floor and in our notebooks just for time," The New York Times senior story editor Liz Day told The Hollywood Reporter. "And also since the documentary aired, we've gotten a lot of information that we're interested in as well that we're interested in pursuing and reporting out further."
The 74-minute production, directed by Samantha Stark, is available in the UAE exclusively on the OSN Streaming app.
The BBC is set to release its own documentary about Spears, with Bafta-winning journalist Mobeen Azhar visiting the singer's home town of Kentwood, Louisiana, before travelling to Los Angeles to interview the fans behind the #FreeBritney campaign.
It has also been reported that competing streaming service Netflix is working on a documentary of its own about the music star.
