'Halo' beauty Beyoncé has admitted that her working relationship with her father, Mathew Knowles, was less than a smooth ride when he was her manager.

Knowles and Beyoncé put an end to their professional partnership in 2011 and she explained to Oprah Winfrey that when she started to speak up for herself under his management, he didn't like it and would override things she booked in:

"It took a while for me and my dad to have an understanding. When I turned 18 and started handling my business more, he went into shock. And we had our issues. I'd say 'No' to something, and he'd book it anyway."

"Then I'd have to do it because I'd look bad [if I didn't]. We would fight sometimes, and it took about two years, to when I was 20, for him to realise, 'Oh, she is an adult now, and if she doesn't wanna do something, I can't make her do it.'"

During the interview for Oprah's Next Chapter, the songstress also opened up about suffering a miscarriage, which is something she talks about in her new HBO documentary 'Life Is But A Dream'. The documentary will air on Saturday, February 16.
