Keshia Knight Pulliam isn't out of the woods yet with her messy divorce ... because her ex just asked for a new trial and threw some shade her way in the process.
Ed Hartwell, a retired NFL linebacker, is begging the court to reconsider its ruling in their divorce -- according to legal docs obtained by TMZ -- claiming he's been asked to pay too much in child support because Keshia has no need for a full-time nanny.
Ed wants to see their kid more and says he shouldn't have to foot the bill for a full-time nanny .
