Singer Rod Stewart has admitted to snubbing several requests to appear as a guest on UK motoring show Top Gear.

The singer has a vast collection of luxury vehicles, but admits he knows little about how his motors work, and he doesn’t want to be caught out on the BBC series.

In his new book, Rod: The Autobiography, he writes: "Mechanically speaking, I don't really know one end from the other. They keep asking me to go on Top Gear - but I'm worried they're going to start talking to me about camshafts and drivetrains and using words like 'torque', at which point I'd be lost."

Stewart also admitted that yoga wasn't for him when his first session went awry as he tried to master a basic move.

He further wrote: "As I was attempting to master a beginner's level 'balancing table' position, I fell over into the fireplace.

"Surely if God had meant us to do yoga, he would have put our heads behind our knees."
