Bah humbug! Days before the Christmas holidays, Beyoncé is apparently planning to take her father, Mathew Knowles, to court over ownership of the Destiny's Child brand, reports In Touch magazine.

Despite firing her father as her manager over four years ago, the 34-year-old superstar's dad still owns the rights to the Destiny's Child name and music — and now Bey wants them back.

“She’s ready to take action,” a source tells In Touch. “Beyoncé is going to sue her own father. She’ll take him to court to show that she deserves the rights to her own band.”

The group was originally called Girl’s Tyme until Matthew took over as manager and rebranded and renamed them. However Queen B is not happy about any of it. The source says, “She feels he basically stole the group and the [trademark] on Destiny’s Child."

The 63-year-old apparently owns at least 25 percent of the Destiny’s Child brand, however, a source says that the percentage may be closer to 100% since Matthew is the one who set up the contract. The outlet is reporting that Kelly Rowland, Michelle Williams and Beyonce would love to do a reunion but they don't want Matthew to profit off of them.

“Mathew wants a Destiny’s Child reunion so he can see another payday,” says the source. “Up until this point, they have let him get away with it, but they want to perform Destiny’s Child music and make their fans happy — without Mathew making a profit.

The source added, “Beyoncé never wanted to sue him, but he’s given her no choice. He won’t allow them to use their own name — unless he gets paid.”

Matthew Knowles is about to get served -- literally!
