 
 Beyonce's father Mathew Knowles, who used to manage the singer, has criticised the handling of his daughter's new album '4'.
Knowles and Beyonce, who had been managed by her father since she joined Destiny's Child in 1997, parted company earlier this year, has expressed worry over the amount her new management.
''The relationship with Beyonce is extremely amicable. I want to make that clear. Where there's concern is the people that she's doing business with. I'm challenging all of these folks on integrity, professional integrity,'' Knowles told the Associated Press.
He added: "She changed almost every aspect of her business. The team ironically appeared to be a cross-pollination of Beyonce's team, Roc Nation's team and Live Nation's team, who ironically have the most to gain." 
Meanwhile, Mathew Knowles recently denied that he stole money from his daughter.
