Beyonce's father, Mathew Knowles, has been pretty quiet since parting ways with his daughter in 2011 after managing her career for many years, but he's recently opened up about how difficult the situation has been.

In a new interview with UK's The Sun, the 61-year-old talked about the business decision to not manage his daughter's career anymore, and the rift that's since developed between the two.

"Normally I hate to talk about anything personal, but it would be a lie if I did not say it has been difficult," he tells the paper. "It was hard for me to let her go. It was hard for both of us to let each other go, and let's be clear on that. She didn't let me go; we both let each other go."

He continues, "This was not a normal ending of a business agreement. This was a dad and a daughter, and it was incredibly painful and it had some difficulties. But I try to always have a positive mind about things and you got to do it the right way."

Besides the problems between Mathew and Beyonce, other drama was also surrounding the family. The singer's mom, Tina Knowles, filed for divorce from Mathew in 2009, weeks after he was accused of fathering a child with another woman.

Regardless of the issues with her parents' marital problems, Beyonce told Oprah last month that she and her father were not seeing eye-to-eye on a lot of things before he stepped down as her manager.

"It took a while for me and my dad to have an understanding," she explained. "When I turned 18 and started handling my business more, he went into shock ... I'd say no to something, and he'd book it anyway ... We would fight sometimes, and it took about two years... for him to realize, 'Oh, she is an adult now, and if she doesn't wanna do something, I can't make her do it.'"
