Britney Spears spoke out on Tuesday about recent documentaries about her life and career, calling them "hypocritical" because they rehash her personal problems while criticising the media for reporting them the first time.
Walt Disney Co's FX network and The New York Times released Framing Britney Spears in February.
The documentary examined the singer's meteoric rise to fame as a teenager, the ensuing media scrutiny and her widely publicised mental breakdown.
This month, the BBC released The Battle for Britney: Fans, Cash and a Conservatorship in the UK.
"So many documentaries about me this year with other people's takes on my life," she said in the Instagram caption of a video of her dancing.
"These documentaries are so hypocritical … they criticise the media and then do the same thing.
"I don't know y'all, but I'm thrilled to remind you all that although I've had some pretty tough times in my life, I've had waaaayyyy more amazing times in my life, and unfortunately my friends I think the world is more interested in the negative.
"Why highlight the most negative and traumatising times in my life from forever ago?"
Film had Spears in tears
In March, Spears said she cried for two weeks after watching part of Framing Britney Spears.
"I've always been so judged… insulted… and embarrassed by the media… and I still am till this day," she wrote on Instagram.
"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 BBC said in a statement its documentary "explores the complexities surrounding conservatorship with care and sensitivity. It does not take sides and features a wide range of contributors."
A New York Times spokesperson declined to comment.
Court battle looms
Spears, who shot to fame in 1998 with the hit Baby One More Time, is in a court battle seeking to replace her father as her conservator.
He was appointed to the role in 2008 after she was hospitalized for psychiatric treatment.
A previous bid to remove him as her conservator failed late last year.
Her fans have shown their support on social media under the hashtags #We'reSorryBritney and #FreeBritney.
The 39-year-old star is scheduled to speak to a Los Angeles court in June.
Her address to the court is expected to be the first time she has spoken publicly about the legal arrangements put in place more than a decade ago.
