Beyonce's dad hit with $1.2 million tax bill

Beyonce is one of the highest-grossing musicians of all time, and her father, Mathew Knowles, managed her career for several years.

Knowles, 61, earned a lot of money in those years -- and an IRS report shows that he owes more than $1 million in back taxes, according to TMZ.

The lien filed against Knowles reports that he owes $485,575.95 from 2010 and $728,004.89 from 2011. In that time, he managed both Beyonce's career and his own record label, among other projects.
