The Britney Spears documentary made Pink think twice about her relationship with the pop music star. The "Just Give Me A Reason" singer appeared on Watch What Happens Live on May 20 and was asked to share her thoughts on the controversial film and the ongoing Spears custody battle.

"I love Britney, but the truth is that none of us know what 's going on," she said. "We are not there."

Pink went on to explain that Spears fans and friends have a sense of "tough protection" on her, which is likely to contribute to anger over her custody battle. However, Pink thinks people should remember that they do not know what is going on behind the scenes. What is important, however, is the happiness of the Spears.

"She is a love," Pink continued. "All I know is that she's incredibly sweet and I want her to be happy."

However, Pink has regretted her relationship with Britney. After watching the documentary, she admitted that she could have been closer to the singer when they had just started their careers,

"I felt sad in those days, I did not know what was happening. I am a strong man, I could have achieved a lot. I could have ... I don't know. "

She continued:

"I do not like to feel helpless or unable to help myself and I can imagine how she felt. Then he really needed support. I would like to go back in time and embrace it strongly. "

However, it seems that the singer is managing to take matters into her own hands. On April 27, the pop icon's lawyer made a request through which the singer will address the court directly. The next hearings are on June 23 and later in July. The news comes almost a month after Britney demanded the "resignation" of her father as the singer's permanent guardian.
