Beyonce's father Mathew Knowles has been accused of failing to keep up with child support payments by the mother of his son.

The former music manager was ordered to pay his former mistress Alexsandra Wright $12,000 (£7,500)-a-month after a paternity test proved he is father of her child, Nixon, who was born in February, 2010.

However, Wright now claims Knowles has missed two installments.

According to California State records obtained by Tmz.com, Wright claims she has been forced to take her son out of school as she can't keep up with the fees without the child support money.

Beyonce's mother Tina filed for divorce from her husband of 29 years in 2009 just weeks after Wright submitted her paternity lawsuit.
