We’re surprised it took this long for some broad to try to cash in on all those Hip-Pop checks by cursing a child with that hairline.

But according to TMZ, a woman now claims that Flo Rida is trying to avoid splitting those checks with her and her child by faking a paternity test.

Mr. Rida is accused of fathering a son with a woman named Gloria Halloway. The kid was born earlier this year.

Flo’s attorney, Sandy Becher, tells TMZ … the rapper took a paternity test last month that ruled him out as the boy’s father … but he used a pseudonym to protect his identity.

But Halloway isn’t buying it — claiming she has yet to see a document with Flo’s REAL NAME on it … and her lawyer, Damon McDougal, tells us, “There is absolutely nothing to indicate that [Flo Rida] was sampled.”

McDougal adds, “I really do feel that the only way we are going to get a reliable paternity test is going to be within the confines of some sort of court order.”

We’re not buying Flo’s story either. Not unless he is running to take a legit test…
