Charlie Simpson was so unhappy in boyband Busted, he almost missed a massive arena concert to rehearse with his new band.

The British group split last year (05) so Simpson could switch his allegiance to rock band Fightstar.

But new bandmate OMAR ABIDI reveals Simpson was bored of Busted long before the split.

He tells SunOnline, "Seeing Charlie before and after he left Busted, was like seeing an entirely different person. He was obviously disinterested in Busted as one day we were writing songs and he was late for an appearance at Wembley with them, because he said he'd rather play with us."
