While co-hosting SiriusXM's Andy Cohen Live, John Mayer discussed Framing Britney Spears and her conservatorship. The Grammy-winning singer admitted in an interview with Billboard that he almost cried five times while watching the documentary.

"It's hard to grow up in front of people. It's just hard," she said. "I was in a place for a year and a half called Van Nuys Psychiatric and you couldn't mess around in there. If you did, you'd get thrown either in the padded room or get put in stretcher restraints and tied up."

5 Paris Hilton

Remember how everyone went crazy back in 2006 when Britney and Paris were spotted partying together? Who would have guessed that these two blondies would stay close friends years later? Anyways, Paris spoke about Britney's conservatorship on SiriusXM’s Andy Cohen Live in September last year. “I think maybe that stems from me being controlled so much, so I can understand how that would feel, and I can’t imagine right now if that was still happening to me. After just working your whole life and working so hard, she’s this icon, and I just feel like she has no control of her life whatsoever, and I just don’t think that’s fair.”

4 Howard Stern

Another celebrity who has spoken out after watching Framing Britney is Howard Stern. "I think I’m #FreeBritney now. I think I’m full-on #FreeBritney,” said the radio host on his SiriusXM show. It is good to see that Stern, who once called Britney a "train wreck", had a change of heart about Britney and decided to speak out.

3 Charlie Puth

Charlie Puth has always been very vocal about how big of a Britney fan is and how she changed pop music, so it was just a matter of time before he spoke out and showed his support. In February this year, the" See You Again" singer finally decided to share his thoughts. "Britney Spears' music was my first exposure to POP music. Her impact was/is profound and it always baffled me as to why people were so brutal to her when she was down," tweeted Puth.

2 Will.I.Am

Will.i.am and Britney Spears have collaborated several times throughout the years — he executive produced her 2013 album, "Britney Jean" and they recorded a club banger "Scream & Shout" together — so it doesn't really come as a surprise that he would speak out on this issue. In an interview with Metro, the Black Eyed Peas member said that the problem lies in "society and the lack of true support and lifting up of the female."

1 Kacey Musgraves
