CHRIS ROCK'S MYSTERY GIRL- DAD SAYS SHE WAS NOT ADOPTED . . . MUM ON MONEY

The biological father of the 7 - year- old girl who lived with Chris Rock and his estranged wife for 7 years tells TMZ the Rock family never adopted the little girl , but he refuses to say if any money changed hands .
Crispen Khanyile says his ex -girlfriend gave birth to Ntombi on February 23 , 2008 ... this according to a private investigator' s report commissioned by an interested party in the case. According to the report , both Crispen and the mother, Precious Ndebele , were unemployed at the time , living on the outskirts of Johannesburg.
The couple had 2 other kids and it appears the situation was increasingly desperate . When the private investigator interviewed Precious last year , she said she was living in a slum and selling secondhand clothes on the streets. The investigator said the conditions were " not conducive for human living ."
Crispen would not discuss the arrangement with the adoptive parents , but simply said we should speak with Malaak , Chris' estranged wife .
It ' s interesting .. . the P .I . says Crispen told him last year Ntombi was living with adoptive parents in the U .S ., but when we spoke with Crispen on Wednesday, it was clear . .. there was NO adoption .
As we reported, Ntombi has been living in the U . S. with the Rock family on a visitor visa , requiring her to return to South Africa once a year . Chris has not seen the girl since he split with Malaak and we ' re told he believes she did something shady to get Ntombi into the U . S .
And one final twist ... Malaak ' s lawyer just broke his silence and said his client is actively trying to legally adopt Ntombi . He did not say when the process started or what has taken so long .
