Britney Spears says she “cried for two weeks” over the recently-released documentary about her career.

Framing Britney Spears premiered in February and examined her mental health problems, the way she has been treated by the news media, and the conservatorship that has dominated her life and finances for 13 years.

The singer has previously addressed the documentary indirectly but she wrote about it specifically for the first time on Instagram overnight.

She said: “I didn’t watch the documentary 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.”

The 39-year-old posted the statement along with a video of herself dancing to the Aerosmith song Crazy, adding that she needed to dance to singer Steven Tyler’s music “every night of my life to feel wild and human and alive”.

“My life has always been very speculated, watched, and judged – really my whole life,” she wrote.

“It takes a lot of strength to trust the universe with your real vulnerability because I’ve always been so judged, insulted and embarrassed by the media, and I still am to this day.”

She added: “Every day dancing brings me joy… I’m not here to be perfect… perfect is boring… I’m here to pass on kindness.”

Spears has been subject to a court-ordered conservatorship since 2008 after suffering two mental breakdowns.

This means her father Jamie Spears, 68, has been in charge of all her financial and personal affairs, temporarily stepping down from the latter role in September 2019 due to health reasons.

A care professional called Jodi Montgomery replaced him on a temporary basis, but the star now wants her to be made her conservator permanently.
