The 'Run It' singer - who is on probation for attacking ex-girlfriend Rihanna earlier this year - was included in the original line-up for the show in Vienna, Austria, but his spokesman insisted hadn't agreed to perform.
However, Jermaine is keen for Chris - who has openly stated what a huge influence Michael has been on his career - to participate and hopes he will be there to perform either 'Man in the Mirror' or 'Thriller'.
He told BANG Showbiz: "Chris has been invited, working out his own situation. He definitely expressed to us he wants to be there. Depends what he is going through with his court case and if a judge will let him leave the country. Chris wants to do 'Man in Mirror' or 'Thriller'."
Jermaine wants fans to forgive Chris for his attack on Rihanna as he believes everyone deserves a second chance.
He added: "Will it be negative if he's there - not at all, he's asked for forgiveness. If Christ can forgive us then we can see people make mistakes. He's a wonderful performer and people need support at these kinds of times."
