Prince caused an internet booking site to crash after it took just 20 minutes for more than 140,000 tickets to be snapped up by fans.
Tickets for the first seven shows of his 21 date O2 Arena residency went on sale at 9AM this morning (May 11).
Within an hour, many fans were selling the £31.21 priced tickets, capped by Prince himself, at five times the asking price on Ebay.
Organisers immediately added a further eight concerts at the arena, which are expected to sell out just as quickly.
The new dates will take place on August 17, 18, 28, 31 and September 1, 9, 12 and 13.
