It's not all doom and gloom! The happiest men in rock

Let's face it, 2012 is turning out to be a bit of a Debbie Downer what with festivals getting cancelled, the government hiking up prices on everything and the continued presence of Jessie J everywhere you look.

With that in mind, we thought what better way of cheering up the good readers of Gigwise than showing off the world's biggest rockstars with huge, cheesy grins on their faces. Come on, if Axl Rose and Billy Corgan can smile from time to time then so can we.

So, from Bruce Springsteen and Green Day's Billie Joe Armstrong larking around on stage to Dave Grohl and Matt Bellamy lighting up the red carpet we've got the great and the good to bare their teeth for us.

In need of a pick me up? Simply take a flick through these pictures, we defy you not to smile along.
