Flo Rida Denies Deadbeat Allegation, Says He's Paying Plenty of Child Support

Flo Rida is calling BS on the baby mama who claims he's a deadbeat dad, saying he already forks over a generous check every month ... and her lawsuit is nothing but a cash grab.

Sources close to Flo tell TMZ he's been making monthly payments of $5k to Alexis Adams to care for their 7-month-old son, and feels blindsided by her taking him to court. We're told Flo and Alexis both agreed on the amount, but he thinks she's being greedy by asking a judge to force him to pay more.

He says they were never a couple.

Alexis acknowledges she's been getting payments, but feels it isn't nearly enough to support herself and the baby -- considering his ailments, and the high cost of living in NYC. She claims she can't afford child care, so she can't leave the baby and go to work.
