X's plea reportedly came eight days after being released from jail.

DMX -- who originally pled not guilty -- copped a plea and pled guilty to attempted aggravated assault (a felony) back on May 22 -- after an incident in which he verbally threatened guards at Tent City, Arizona, back in February. The serial law breaker is due back in Maricopa County court for sentencing on Monday. (TMZ)

The rapper's incident reportedly took place while he was in lockdown.

Joe Arpaio says Simmons became upset Sunday after being told he could not have a meal he took from a serving tray. Arpaio says Simmons then threw the tray and its contents at an officer, who wasn't injured. Simmons has been on a bread and water diet as punishment for an earlier jail violation. (Associated Press)

X previously stated his innocence regarding the assault.

"Many of you know me as DMX but right now I am speaking to you as Earl Simmons," he said in a statement. "For the record, I want to state 'I Did Not' physically touch or hit an officer. This is just another attempt to destroy my credibility." (Statement)

Currently on an appearance tour, X recently spoke on returning to hip-hop.

"Just love what you do man," X explained. "Do it for the love of it and you'll get there eventually. You know what I'm saying? That's what it is, man. Gotta keep it one hundred. I've been locked up for a few months, so I ain't really heard [about rock and hip-hop fusing] you know what I'm saying? So I'm waiting to hear it, once I hear it, I'll let you know how I feel about it. I was born ready for this [tour] man. BFW, 'Built For War' that's what we do all day, it's nothing. It's not a motherf*cking game man, this is what we do. It's what we built for, it's how we get down. Real talk. That new [Jadakiss] and Swizz [Beatz] joint, you know what I'm saying? 'She's phony, she's fake, she's fake, that's the type of people I hate.' Aigght? I'm on the remix, check that sh*t out son, real talk." (AllAZHipHop)
