Michael Jackson is reforming the Jackson 5, it has been claimed.The eccentric singer is said to have been visited in Las Vegas by his brothers, Jackie, Jermaine, Tito and Marlon, who put forward the idea of getting the band back together for a tour.Michael's sisters Janet and Rebbie, and his other brother Randy - who was part of the Jacksons - were also at the family reunion and are keen on joining their siblings for a Jackson family tour.US gossip columnist Roger Friedman said: "A successful Jackson family tour could change everything for Michael. It would also be a financial boon for the whole family. The tour idea also works for Janet, whose last two albums have been huge disappointments."The idea of Michael and Janet performing a couple of duets, or Janet'sbrothers backing her on her own hits would be a tantalising prospect."Michael has been desperate to re-launch his career since being acquitted of child sex charges in 2005. He was previously in talks about a live residency at a major Las Vegas hotel and casino but the negotiations have since stalled.
