Chris Rock is facing some bizarre questions when it comes to the origins of a 7-year-old girl who lived with his family, according to TMZ.

The comedian and his now estranged wife, Malaak Compton Rock, brought a 6-month-old South African girl named Ntombi to the United States to live with their family back in 2008. Most assumed the family adopted the young girl, but there is no evidence to suggest the Rock family ever went through legal proceedings to do so.

After doing some digging, TMZ discovered that Ntombi originally entered the US on a B2 "visitor for pleasure" visa in 2008, which typically allows visitors to stay in the country for up to 1 year. Their sources learned that Ntombi would return to South Africa with Chris's estranged wife, Malaak, yearly, and visit with the girl's biological family, including her mother, father, brother and sister, before always returning back to the US.

Chris and his family were seen with the young girl over the last seven years, bringing her out to red carpets. Ntombi seemed to be treated just like Chris' two biological children, up until the couple began going through a divorce last year. Sources say that Chris hasn't seen the child in question since he and Malaak split, though he sees his two biological children regularly.

When Chris and Malaak's divorce proceedings began, South African officials simultaneously started investigating how Ntombi came about living with the Rock family in the US. They are looking into whether or not a legal adoption took place. For Chris' part, his rep told TMZ that Chris does not have an adopted child.

Sources close to the former couple claim Chris never signed any documents, and that this was the doing of Malaak.
