DMX's team says, "In his ongoing commitment to putting family and sobriety first, DMX has checked himself into a rehab facility. He apologizes for his cancelled shows and thanks his fans for their continued support."

The New York-born rapper was scheduled to perform Saturday at the reunion concert for Three 6 Mafia in Memphis and Day 2 of Rolling Loud in New York on Sunday. Both appearances have been canceled. The Ying Yang Twins replaced X Saturday night.

DMX has had a long, difficult struggle with addiction. He's been jailed numerous times in the past over drug-related offenses and has spent time throughout the years in rehab.

X was released from prison in January after serving time for tax evasion. Just before his release, he talked about how badly he wanted to see his youngest son, 3-year-old Exodus Simmons, who at the time had serious health problems. X has 15 kids.

He also said he was getting offers from movie producers for a biopic.
