keyshia cole (head bent)

*Earlier we reported that Keyshia Cole was headed to jail for a penalty she committed over a decade ago, but at the time of our posting, we didn’t know what the infraction was. Now we know.

Here’s the deal. Cole faces jail time over a DUI she got a decade ago … and no one would have known had she not flown into a jealous rage in Birdman’s condo and got arrested for it.

Earlier this week, Cole was in a L.A. County court trying to explain to a judge that a very old arrest warrant was a gigantic mistake. The warrant was issued in 2004, because she failed to submit proof to the judge that she completed her alcohol ed class after a 2002 DUI conviction, reports TMZ:

Keyshia’s lawyer tried explaining the singer completed the course, but the judge was unmoved. There was no paperwork to prove it, so the judge indicated he’d throw her in jail for 30 days.

But the judge also showed some mercy, telling Keyshia’s lawyer he would let her skate if they could submit proof she finished the classes. A hearing is set for February.

Now here’s the hitch. Authorities had no idea there was a warrant and probably wouldn’t know, but when Keyshia was arrested in September for assaulting a woman in Birdman’s condo, cops did a warrant check and … bingo.

Dang, that just about says it all. Need we say more? Nope. Case closed. Bye Keyshia!
