Usher ex 'incapable of being a proper parent'

Usher's attorney has labelled his ex-wife Tameka Foster "incapable of being a proper parent" to their children.

The former couple was in court this week for the latest stage of their ongoing custody battle over sons Usher V, four, and Naviyd, three.

Singer Usher - who is seeking sole custody - had accused Tameka of trying to interfere with the time he was allowed with their kids under their joint custody arrangement--a charge she denied.

During closing arguments on Thursday (16.08.12) in a Fulton County, Georgia, the legal representative said she "does not have the emotional stability or capacity to bond with them, and therefore she is handicapped," according to MyFox Atlanta.

Tameka's attorney, counter argued that Usher travels all the time and does not have a good relationship with his mother, whom he had testified was part of the family unit that would help take care of Usher V and Navyid when he was on the road.

On Tuesday (14.08.12), Tameka --who is looking to retain joint custody and have her monthly support payments increased from $8,000 to $11,000--testified that she "begged" her ex not to seek sole custody.

She said: "I was like, 'It's ridiculous, are you mad me? I don't know why. You know your kids are fine. They're happy. They're productive. They read, they spell. They're clean, they're fed.' Maybe I don't do everything perfectly, but I do the best I can."
