Speaking to fans outside the Los Angeles dance studio where he's rehearsing for the gigs, the singer admitted that he might not be physically well enough to complete all 50 shows, reports Britain's The Sun.
"I don't know how I'm going to do 50 shows," he said of the gigs, which kick off in July. "I'm not a big eater--I need to put some weight on."
The star then laid into the gig promoters, saying he only wanted to play 10 shows at the O2 Arena.
"I'm really angry with them booking me up to do 50 shows," he said. "I only wanted to do 10, and take the tour around the world to other cities, not 50 in one place.
"I went to bed knowing I sold 10 dates, and woke up to the news I was booked to do 50."
Michael Jackson has already postponed the start of the residency from July 8 to July 13, citing production issues.
