Usher Raymond and his ex-wife Tameka Foster Glover Raymond are still battling it out in court in the child custody battle that began last year.

You may recall that the two were arguing over everything from Tameka’s Sak’s discount to Usher’s “alleged” drug use.

In the midst of the dispute, they even held separate birthday parties for their youngest son, Naviyd’s 3rd birthday party last December.

The former lovebirds appeared in Fulton County courthouse in downtown Atlanta earlier today where there were given an ultimatum by a Superior Court judge: come to an amicable agreement… or else HE will do it for them!

Details:

TMZ was on the scene today as the singer and his ex-wife showed up to court this morning where a judge ordered them into private mediation.

The two then went into the judges chambers to try and hash out a temporary custody agreement in lieu of all of their demands.

They’ve had all morning to work something out — but if they don’t come to terms soon … they’ll face the judge again this afternoon … when he’ll impose a temporary order, deciding how Usher and Tameka will split their time with their kids.

The order will also address child support.

As we’ve reported, Usher and Tameka have been fighting over their kids for years — Tameka wants full custody, claiming he secretly uses drugs. Usher has denied the allegations, asking for an increase in daddy time. The couple currently shares custody.

So far there’s no word on IF the two finally came to some agreement but one thing I know (that TMZ didnt say) is that it was Usher who initiated the custody battle last year.

UPDATE: *as of 6pm, Usher and Tameka had failed to come to a resolution. Mediation will resume tomorrow.

I’ll keep you updated…

Just for the record, Usher has been playing it safe when it comes to his relationships since he’s been on that worldwide comeback trail.

Ursh and his camp are in agreement that it’s best to keep his relationship under wraps for now. Clearly since he caught so much flack with his very public marriage to/divorce from Tameka, they all realize that Usher is much more marketable as a single man.

He even claimed to be “single” in an interview just last month…

He’s no dummy, that’s for sure…. Thoughts?
