Michael Jackson's series of 10 concerts at London's O2 arena in July will be "the final curtain call", he has said.
He told fans at the venue: "This is it. I just want to say that these will be my final show performances in London."
The pop superstar, 50, may take the show around the world, but that would be his last tour.
He made a five-minute appearance in front of hundreds of screaming fans to announce 10 the London dates, which will earn him more than $50m (£35m).
His first words to fans were: "I love you so much.
"This will be it. When I say this is it, it really means this is it," he added.
"I'll be performing the songs my fans want to hear. This is the final curtain call."
The first concert will be on 8 July, with tickets costing between £50 and £75. They go on general sale on 13 March.
The star will put on a "big budget, grand, highly technical, incredible show", according to Randy Phillips, chief executive of promoter AEG Live.
"Michael Jackson is a perfectionist so it's going to be amazing," Mr Phillips told BBC News. "He'll try a lot of new things."
Asked whether the London dates would be his last ever performances, Mr Phillips replied:
"These will be the last shows in London.

"Whether he will go on from here around the world... this will be his last tour. All he's agreed to are the London shows at this point."
The star was "in great shape" for the dates, he said.
"He's passed an extensive four-hour physical with independent third party doctors selected by the insurance carriers. He's in incredible health."
Mr Phillips added that AEG had a "broader relationship" with Jackson, which could involve a new 3D film based on Thriller as well as future concerts.
The three-and-a-half year plan could earn Jackson more than $400m (£283m), he predicted.
The singer had been due to appear at the O2 at 1600 GMT, but only left his central London hotel at that time and arrived an hour and a half late for the announcement.
Several hundred fans waited at the O2 to see him, and said they were not disappointed by his brief appearance.
