A Jackson 5 reunion could be a major money-spinner for the brothers
Michael Jackson is to take part in a Jackson 5 reunion tour, his brother Jermaine has said.
Jermaine told the Australian Associated Press it would be "a family affair", with sister Janet the opening act.
"And of course, the original Jackson 5... Michael, Randy and the whole family... we're in the studio, we're planning on being out there next year."
But Jermaine has said similar things before, in 2003 and again last year, and a tour has so far failed to happen.
"This has been a long time coming for the Jackson family to get back together," Jermaine said.
Rumours of a reunion have circulated for years.
The last time the original members performed together was at a concert in 2001 to celebrate Michael Jackson's 30 years in music.

But Michael has kept a low profile since being cleared of child abuse in 2005.
He worked on a charity single for the victims of Hurricane Katrina later that year, but it never materialised.
He was also working on a new album, with current US stars such as Akon, John Legend and will.i.am writing songs for him, but the status of that project is unknown.
If a Jackson 5 tour did take place with Michael, it would be a major draw for fans, and a massive money-spinner for the brothers.
The Jacksons - featuring Tito, Marlon, Jackie, Jermaine, Michael and Randy - found fame in the 1970s with hits such as I Want You Back, ABC and Shake Your Body (Down To The Ground).
Michael's success eclipsed that of his brothers in the 1980s, while sister Janet also rose to prominence.
