The star spent Wednesday night showing bosom buddy JONATHAN WILKES support on the first night of his starring role in the We Will Rock You UK tour.
And when asked backstage if he’d ever sing again with GARY BARLOW and the boys, he replied: "Yeah, of course I would."
Robbie, who clearly loves a bit of razzle-dazzle, brought along a bus rammed with women – including his mum Sandra and girlfriend AYDA FIELD – for the big night out in Manchester.
Later, he went backstage to meet some of glamorous cast and posed with Wilkesy and QUEEN stars BRIAN MAY and ROGER TAYLOR.
But Rob didn’t hang about. He made a sharp exit at midnight in his purple bus.
He had to get away early because he was in the studio yesterday with MARK RONSON working on new material. link
