Andre Iguadala and Clayanna Warthen

NBA star Andre Iguodala already pays his baby mama $18,000 a month in child support, but she wants the Golden State Warriors star to cough up even more cash for their 6-year-old daughter, London.

According to gossip tabloid TMZ.com, Clayanna Warthen receives $18,000 a month in child support from Iguodala. But that isn’t enough — she says — to pay for London’s expensive school tuition.

So Warthen is headed back to court to convince a family judge to hike her monthly child support payments to $58,000 a month.

Warthen claims their daughter is a genius with a 151 IQ. But she says Iguodala virtually ignores the child and refuses to pay more than the $18,000 monthly payments he is required to pay her by court order.

TMZ — “We’re told Clayanna Warthen claims she can’t even fully pay for their 6-year-old’s school expenses on the $18k a month he’s paying in child support. She also says he won’t let little London even meet her other half-siblings.

Warthen — who had a 6 year relationship with the Golden State Warriors player — wants the monthly support hiked to $58k a month, claiming it fits the court’s child support schedule since Andre makes around $11 million a year.”
