But his bandmates are said to be unhappy
But the model’s decision has apparently upset the rest of the band.
‘Poor Jamie is wedged between a rock and a hard place,’ a source tells the Daily Mirror.
‘He wants Kate with him as his girlfriend but at the same time he’s desperate to keep things strictly professional.
Kate, 35, regularly joined ex-boyfriend Pete Doherty, 29, on stage when they were together.
And it’s thought she may perform with Jamie, 40, too.
‘He has promised Kate that if she comes out to Australia he’ll include her in the music.’
