DMX has reportedly canceled several show dates due to a "medical emergency." 

According to TMZ, DMX canceled his Tuesday night stint in Santa Ana, Calif. and will postpone his Wednesday and Thursday gigs on the West Coast due to an unspecified medical issue.  

Billboard was in attendance for the Ruff Ryders Reunion concert at Brooklyn's Barclays Center on Friday (April 21) and reported that the New York rapper struggled through his headlining set, where he launched into several rants. He screamed at one point, "Don't expect me to be a f--king role model!"  

DMX has experienced several medical emergencies in the past. Last year, he was hospitalized following a reported asthma attack that stemmed from alleged drug use. His camp denied substance abuse while Ruff Ryders collaborator Swizz Beatz tweeted that X was "in good spirits." 

The "Party Up" MC is also slated to headline the Brooklyn Hip Hop Festival in July. 

Reps for DMX have not immediately responded to Billboard's requests for comment.
