iHeart Radio Music Festival, Day One: Green Day Freak Out, Plus Lil Wayne, PSY & No Doubt

By: X. Alexander / September 22, 2012

With all that talent churning around Las Vegas this weekend, what could possibly go wrong? Believe it or not, there is a drawback to having so many huge acts performing in one space over just a couple of days — trying to squeeze all that showmanship into a set short enough to make room for the others, which already prompted at least one meltdown from Billie Joe Armstrong. When Green Day‘s set was cut short to make room for the next act, “Oh Love” turned to “No Love,” complete with guitar-smashing and a profane sh0ut-out to poor Justin Bieber.

Was Billie Joe truly upset, or was it all for the sake of entertainment? Perhaps a little of both? Fortunately, the rest of the talent was better-behaved, with an appearance by a husky-voiced Britney Spears, No Doubt performing their next Push & Shove single “Looking Hot,” Ryan Lochte (and his grill) joining Miley Cyrus to introduce Lil Wayne, and of course, the suddenly-everywhere viral sensation PSY doing “Gangnam Style.” Catch all this and more below.
