America's Got Talent season eight TV billboard...

Last season the arrival of 'shock jock' Howard Stern shook up things at America's Got Talent.

This season Sharon Osbourne is out and Project Runway's supermodel host and judge Heidi Klum and former Spice Girl Mel B join Stern and Howie Mandel on the show's judging panel.

The extra judge means it may be even tougher for contestants to get three votes to progress through to the next stage of the competition, but the extra dose of honesty and bluntness from the new judges should add some fun for the eighth season.

Another big change for the reality talent contest is that hopefuls will now perform center stage at the historic Radio City Music Hall, which should give some gravitas to proceedings.

This season eight billboard was snapped along Sunset Boulevard on May 10, 2013.
