"I’ll be performing the songs my fans want to hear.
"This is the final curtain call.
"I’ll see you in July.
"This is it."
You can watch his speech in the video below:
Jacko was an hour-and-a-half late for the press conference and was only on stage for a matter of seconds. After speaking he told fans that he loved them.
He didn’t give full dates, but immediately afterwards a statement was issued confirming Jackson would play 10 shows at the 02 arena “performing in London for the last time”.
It read: “Michael Jackson has not played a series of concerts since he last toured 12 years ago.
“These dramatic shows promise an explosive return with a band of the highest calibre, a state-of-the-art stage show and incredible surprise support acts.”
The 10 concerts will begin on July 8 with ticket prices at £50-75 plus booking fees.
The 50-year-old is expected to pick up around £5million from each gig, which will go towards paying off his debts.
Jackson has lived the life of a virtual recluse since his acquittal of child abuse charges at a 2005 trial.
His increasingly bizarre behaviour coupled with questions over his health have overshadowed his musical output, including a recent 25th anniversary re-release of classic album Thriller and 2001 record Invincible.
The Sun revealed exclusively last month that Jacko had a severe staph infection, like MRSA. He may have contracted it during nose reconstruction surgery.
The star has also been plagued by child sex allegations. He was cleared of all charges at a criminal trial in the United States four years ago.
His last appearance on stage in London was at the World Music Awards, where he was booed for only singing a couple of lines of hit We Are the World.
Bookmaker William Hill is already offering odds that he won’t complete this run of concerts.
Despite these fears, Michael’s loyal fans are supporting him 100 per cent.
Shuhena Begum, who travelled from Birmingham to the o2 to see her hero today, said: “Of course it’s worth it.
“My whole family is mad about Michael – he’s the greatest.”
Jackson is one of the biggest musical acts of all time, selling an estimated 750 million albums. Thriller, released in 1982, is the best selling album of all time.
