Tameka Foster and Usher are in a custody rights battle over their children Usher Raymond V and Naviyd Eli Raymond.  Foster is starting to fight dirty by accusing Usher of drug use.

Back in January Usher had a little mishap on stage in Germany and was booed off stage.  Foster believes he was high during the incident.  She is now insisting he take a drug test to prove her point, “I believe he gets high. And if he doesn’t then he’d take the drug test, correct?”.

Usher is refusing to take any “frivolous and unfounded,” drug test because he believes Foster is just trying to “harass and embarrass” him.

In your opinion, does Usher seem to be under the influence?
