Lil Wayne may have yet ANOTHER illegitimate child running around — this according to a Missouri woman who hit Weezy with paternity papers while the rapper was serving time at Rikers Island. According to tmz.com,Weezy was supposed to get tested before September 10, 2010 … but since he was behind bars at the time he got the letter (dated August 20), the judge pushed the deadline to December 9.

But the story doesn’t end here, get this…The woman going after Wayne is the child’s grandmother!!

Wayne has fathered 4 other kids, that we know of!!
