Despite his spokeswoman labeling the reports speculative, Michael Jackson is likely to perform a series of comeback concerts in London this summer.
A announcement regarding the engagements is expected to be made Thursday by the musician himself.
Jackson's last live performance in Britain took place at the 2006 World Music Awards, where he appeared only briefly.
The O2, formerly the Millennium Dome, is expected to be the venue for his concerts. Also due to headline there in June, for eight nights, is Britney Spears
