On Friday night in New Orleans, Britain's Kaiser Chiefs wrapped their series of dates supporting Green Day with a spectacular finale that included a stage invasion and a superstar sighting.

"Brad Pitt was there," Kaiser's drummer Nick Hodgson told Spinner Saturday morning. "It was totally cool. We met Brad Pitt."

Hodgson explained he ran into the star as the actor came out for the show. "He had his kids with him," he said, kindly declining our request to tell us which Brangelina spawn were in attendance (although he noted they had headphones on). "[There were] a couple security and that, but he was just sat in the normal seats."

Although the Kaiser Chiefs are big stars in the native England, headlining festivals and topping charts, Hodgson revealed his band couldn't help but feel star struck over the leading man. "We had a photograph taken just like regular nerds," he said, before revealing that act didn't come without a little trouble. "We had the camera set to video so we had to call him back. He was cool. It's not the first time [that's happened]."

But the Pitt sighting wasn't the only momentous part of the night -- Green Day also gave the Brits a goodbye hazing. "Every time they when they have support bands, the final night they sort of prank the band. We got off really lightly I think. If you look at YouTube, there's some support bands that have had bad things happen to them, but [Green Day] organized a Louisiana/New Orleans old time brass band and they got them into the arena last night," Hodgson recounted.

The brass ensemble was kept hidden, however, until they invaded the Northern English boys during one of their final songs, first album favorite, 'I Predict a Riot,' which the extras joined in on in old time fashion.

"When we started 'I Predict a Riot,' this band came on and then Green Day came on, and they were playing cowbells. It was a shock," Hodgson laughed. "I just wonder whether the people of New Orleans think that's our regular type of performance."

But the hazing didn't end there. "Toilet Paper. They T.P.'d us," Hodgson said of Green Day's on stage sayonara. "[They covered our] drums, instruments. It was live on stage. We got T.P.'d."
