The fivesome rose to fame after they placed third on Britain's The X Factor in 2010, and soon became superstars all over the world.
Their popularity has been compared to another all-male band to come out of the U.K., legendary rock group, The Beatles, whose catchy songs and good looks attracted crowds of screaming teenagers all around the globe.
In an interview with Britain's Event magazine, Styles admits that while his band's rise to fame is similar to that of the Fab Four, he insists their music is completely different.
He says, "We all sat and watched the film of them arriving in America. And to be honest, that really was like us. Stepping off the plane, the girls, the madness. It was exactly the same as when we got there - just 50 years earlier.
"But none of us think we're in the same league as them music-wise. We'd be total fools if we did. Fame-wise, it's probably even bigger, but we don't stand anywhere near them in terms of music."
