Lil Wayne smiles before the start of the second half of an NBA basketball game between New Orleans Hornets and the Miami Heat in New Orleans, Friday, Nov. 5, 2010.

*The grandmother of a Missouri woman who accuses Lil Wayne of fathering her 8-year-old child obtained a court order requiring the rapper to submit to a DNA test, reports TMZ.

Weezy, already the father of four, was reportedly hit with paternity papers while serving time at Rikers Island.

According to the legal papers, obtained by TMZ, the artist was supposed to get tested before September 10, 2010, but since he was behind bars at the time he got the letter (dated Aug. 20), the judge pushed the deadline to Dec. 9.

“The woman going after Wayne doesn’t explain why her daughter isn’t pursuing the test herself — in fact, the birth mother’s name isn’t even listed on the documents,” according to TMZ.
