Rocker Jon Bon Jovi lost his cool earlier this year (12) when U.S. President Barack Obama offered him a ride in his infamous armour-plated Cadillac.

The Bon Jovi frontman is a longtime supporter of the American leader, even raising $3 million (£1.8 million) for the Democrat's campaign efforts in 2008.

He flew to New York for a fundraiser on presidential jumbo jet Air Force One this year (12), and during the trip he was allowed to ride in Obama's bombproof limo, nicknamed The Beast - and the experience left the singer overjoyed.

He tells Britain's Daily Mirror, "I go to the Waldorf (Hotel) and sing and I go to the van with the staffers and the girl comes running up and says, 'They want you in the Beast'.

"So I say 'cool' and I'm in the Beast with President Clinton and President Obama. Air Force One is cool but the Beast is cooler. Sinatra's not done that.

"I wanted so badly to get my phone and take a picture. I wanted to press my face against the window as we went through Times Square so everyone could see me."
