Olly Murs was a contestant on The X Factor in 2009

Olly Murs spotted One Direction fans rifling through the boys' rubbish when he was on tour with them in America.

The singer was shocked by the 1D frenzy across the pond.

My fans aren't as obsessed as theirs,' says Olly, 28.

The infatuation and just how much they fancy One Direction was crazy. I caught fans going through bins trying to find stuff the boys had chucked out.

It was insane but the fans were brilliant to me.'

Despite the madness, the Xtra Factor host loved being on the road with the teen group.

It was intriguing to be in the mayhem of what was going on and to see the impact they've had,' Olly tells Metro.

It was an easy six weeks work - the guys were great and so were the fans.'
