Beyonce's father has insisted he isn't a ''deadbeat dad.''

Matthew Knowles has hit back at allegations he owes $24,000 in child support to his former lover Alexsandra Wright for their three-year-old son Nixon, whom he has never met.

Sources close to the music manager told gossip website that messed up paperwork is to blame for the dispute.

Matthew, who is set to appear in court in Los Angeles on Friday (13.12.13) in relation to the child support row, was said to be two months behind in his maintenance payments.

However, he has told friends that he made the payments slightly late, but past the deadline for being credited, so it only appears like he hasn't paid what he owes.

Matthew is now reportedly behind for his December payment, which was due on the 1st, but plans to pay the full $12,000 before it officially becomes delinquent.

In 2009, Beyonce's mother Tina filed for divorce from Matthew after he reportedly had an affair with Alexsandra, who fell pregnant and requested a paternity test.

Beyonce, 32, and sister Solange, 27, didn't attend their father's wedding when he re-married earlier this year, tying the knot with former model Gena Charmaine Avery in Houston, Texas in June.
