It's REAL drama for DJ Drama!  The popular Atlanta based DJ known for doing tons of mixtapes with T.I., Nelly, Jim Jones, Rick Ross, and pretty much any other rapper in the game, has found himself caught up in some ish.

TheYBF.com just received EXCLUSIVE details about Drama allegedly cheating on his wife with a 21-year-old...and the shocking offer we're told he made just to cover it up!

DJ Drama--aka Tyree Simmons--married his former video vixen wife, Summer Walker (above), 3 years ago.  We've learned his weekend traveling for work allegedly had a little booty action on the side.  Surprise surprise.

Any given weekend from Thursday to Sunday, DJ Drama usually travels around the country DJ'ing parties at different clubs.  Apparently this is how he met the alleged 21-year-old mistress who lives in Kentucky.  We're told she is one of many "pretty" girls who allegedly get paid by club promoters to party with the celebrity guests.

TheYBF.com has exclusively learned that the woman in question (above with DJ Drama) claims she cheated with Drama, and he got her pregnant.  The mistress informed Summer that she is now 4 months pregnant.

How did Mrs. Drama learn about her hubby getting caught up?  Because little miss (alleged) mistress did what any 21-year-old would do--she sent Summer a Facebook Message!

But get this: DJ Drama apparently didn't want anyone (including his wife) to know about his alleged transgression.  We're told Drama offered little miss (alleged) mistress $10,000 to end the pregnancy...and to keep quiet!  Needless to say, she is keeping the baby and told Summer she simply "wants Drama to be a good father to their baby." 

Drama's alleged jumpoff (in the pic directly above)--who ironically has an entire photo album she uploaded a year ago to her Facebook Page entitled "Partying with Dj Drama and the crew"--had a twitter exchange with Summer about the situation a couple days ago.  Summer's response?

@MsShalaEdwards you are dumb and you will pay for what you have done. Please don't underestimate me. That would be your downfall

Summer went on to say, "When women have babies just to see what they can get from the man it always ends badly....but hoes will be hoes.  Devising a plan around selfishness will only get you caught up...its called the short end of the stick."

Mrs. Drama is devastated and plans to end the marriage.  Especially because, according to Summer, she's been Drama's right hand in most of his business matters for the last 3 years.  And has cared for his kids from previous relationships as if they were her own.  Summer is currently on her way back home to Texas to be with family.  She and DJ Drama have no kids together.

We reached out to Drama about the situation, his reps offered "No comment."

The Holidays always bring out the best in folks don't they?
