Simon Cowell Talks 'Amazing' New One Direction Video, James Arthur, Little Mix, More

Simon Cowell has hit Twitter hard with high praise for several of the acts he's in charge of - One Direction, Little Mix and James Arthur among them.

The mogul also took the time to voice his appreciation for Fifth Harmony, Emblem3, Leona Lewis, Susan Boyle and Labrinth as he had a late-night gushing fest.

As part of his barrage of tweets, he called 1D's new music video "amazing", and claimed that Leona Lewis delivers her best ever vocal performance on her upcoming Christmas collection. He did, however, accidentally call her 'Leonard Lewis' first time around.

He also confirmed that Susan Boyle has got a duet with the late Elvis Presley on her new LP, adding that Labrinth is a "genius".
