The Jacksons will reunite at the Michael Jackson tribute concert.
Jermaine Jackson - who shot to fame in The Jackson 5 alongside his brothers Jackie, Tito, Marlon and Michael - has refused to rule out joining his musical family on stage at the show he is planning in Vienna, Austria, on September 26.
When asked if he plans to perform with his siblings, Jermaine said: "That could be one of the surprises.
"Being a producer I wanted to put a show together because it is a family thing. My family is very busy, Janet is doing something right now. I have invited all of them, so, you never know - once the music hits them they will probably want to come up and perform and do what they know how to do. But definitely I have committed myself to performing."
Jermaine revealed he has invited his mother Katherine Jackson to the event, along with Michael's three children - Prince Michael I, 12, Paris, 11, and seven-year-old Prince Michael II, also known as 'Blanket'.
He added: "I spoke to my mother and I said I wanted to do something for the fans in Europe. She has supported this from the very start."
