Not only will the original Take That line-up - Gary, Robbie, MARK OWEN, HOWARD DONALD and JASON ORANGE - play together for the first time in almost 15 years but ex-BEATLE Sir Paul is teaming up too.
A source said: "The reunion is go. Robbie is utterly thrilled about it. He's been dreaming of performing with Take That again for years and now it's going to happen."
So, how did it that big reunion go, exactly?
Not at all, it turns out:
Robbie Williams has joined his former Take That bandmates on stage at the Children in Need charity concert, but there was no reunion performance.
