Usher’s ex-wife, Tameka Foster Raymond, is lashing out at the R&B superstar in the wake of a ruling in their prolonged child custody spat.

“Money can buy many things… But in the end. Truth & goodness will prevail. I must continue to believe this. Stand firm,” she wrote on Twitter.

This message was followed by: “A woman’s loyalty is tested when her man has nothing… A mans loyalty is tested when he has everything!”

“Don’t fear the enemy that attacks you… Fear the fake friend that hugs you. There’s not much worse,” she added.

The custody battle concluded just weeks after the tragic death of Tameka’s 11-year-old son Kile from injuries sustained in a jet ski accident.
