Keshia Knight Pulliam claims her estranged husband, Ed Hartwell, won't take a paternity test and she wants him locked up for it. Pulliam just filed new docs saying she's already submitted her court ordered DNA sample ... but Ed missed the deadline. She wants a judge to find him in contempt, and lock him up until he hands over his sample. That's not all ... Keshia wants Ed to register all his

guns solely under his own name. They previously had weapons registered together, but Keshia wants to cut ties due to what she calls Ed's uncontrollable temper. Keshia's also asking the judge to order Ed to pay half her moving fees and household bills from the home they shared. And if you wanna know how petty this split is - she's demanding he buck up for her pooch's "flea treatment."
