Yesterday, it was revealed that Usher Raymond‘s ex-wife/mother of his two sons, Tameka Foster Glover Raymond had filed “Papers” seeking to gain full custody of their children.

Well it over yet… the saga continues in the Raymond vs. Raymond custody battle.

Today it’s being reported that Tameka is about to spill all the TEA on Usher and has even accused him of doing drugs and requested for Ursh to submit to a drug test!

Of course you already know Usher respectfully declined to pee in the cup. 😆

Ooooh this is about to get gooooood (pass the popcorn)!!

Details….

It’s somewhat customary in a custody hearing for one or the other to ask for a drug test. Normally the other parent will comply (especially if they’re clean and sober) but reportedly Usher flat out refused!

Tameka claims she saw Usher with “drugs” with her own eyes and reveals in recent court documents that she caught her ex husband with “mysterious pills in his jeans pockets” back in 2008.

As further proof of her claims that Ursh be partaking in extracurricular druggy activity, Tameka refers to Usher’s controversial Berlin concert, saying she believed “he was wasted during the Germany concert”.

If you recall, back in January video circulated online of Usher appearing confused during the European leg of his OMG Tour.

Usher was unable to sing and dropped the mic and exited stage left like Bishop Eddie Long.

He later apologized to fans, and his reps blamed a respiratory infection for his inability to perform.

Tameka feels that episode is PROOF that he was under the influence of something… but what? nobody knows.

“I dated him . . . when he’s had a very serious throat condition and he still performs like a champ,” she said.

“ I really feel strongly that something was going on there, and it wasn’t, ‘Oh I have laryngitis.’ ”

She made a further claim in the deposition: “I believe he gets high. And if he doesn’t then he’d take the drug test, correct?”

Usher filed a response to Tameka’s drug allegations last week and said her request for a drug test is “frivolous and unfounded,” and intended to “harass and embarrass” him.

I dunno y’all…. I’m starting to think Tameka has something on Usher. This drug testing request didn’t just come out of nowhere (and he IS a celeb, so… it’s NOT out of the ordinary).

Hmmm… Could Usher be a druggy?

I guess we’ll never know if he won’t take the test…
