The Leeds-born presenter has kept a low profile for much of the period since he left the breakfast show in September 2012, to be replaced by Nick Grimshaw.
Apart from a stint of touring with the stage production of Jesus Christ Superstar, Moyles has been largely out of the public eye apart from posting videos to his YouTube channel.
But he assured his fans he had been “doing plenty” and would let them know what he had been working on when the time was right.
In a message he posted on Facebook, he explained: “Contrary to popular belief I am actually quite busy with my life. “Just cos I’m not on the radio anymore people think I’m doing nothing. I wish.”
