UPDATE: The Doobie Brothers say this isn't true.

We all know (or if not, you're soon to learn) about Michael Jackson's knack for using the hottest guitarist of the moment as guests on many of his albums. But apparently, the King of Pop paid the rock world back -- secretly -- by singing background vocals for the Doobie Brothers.

Reportedly, he can be heard on such Michael McDonald-era tracks as 'Minute to Minute,' 'What a Fool Believes' and 'Here to Love You.' There's even a video showing him bragging about his big secret to (noted rock and roll lover) Liz Taylor.
