Jennifer Hudson in heated custody war with ex, David Otunga

She’s playing hardball with her custody battle from here on out.

Jennifer Hudson, 37, is refusing to help fund her former partner David Otunga’s housing costs, according to The Blast.

She’s also vehemently disputing his claims that he’s the primary caregiver for their nine-year-old son David Daniel Ortunga.

Ortunga, 39, has claimed that he has been their son’s primary caregiver all along, as Hudson’s busy acting and singing schedule has often kept her away from home.

But Jennifer Hudson’s legal team is countering her ex’s claims, saying that he was also often on the road for his job as a wrestling commentator for the WWE.
