The music mogul was visited by the British boy band on the ‘American Idol’ set – where Simon is filming his last series as a judge on the show – and was full of praise for the foursome as he introduced them to host Ryan Seacrest.
Speaking about JLS, the 50-year-old star said: “They’re hard working, they respect their fans, and they’re super, super talented. They’ve sold about two million records and I think they might break in America.”
JLS were the runners up on Simon’s 2008 ‘X Factor’ show – the pop star search programme he is launching in America next year – and have since scored two number one hits in the UK singles chart and a UK number one album.
The ‘X Factor’ also gave the world Leona Lewis, who won the series in 2006 and went on to become a huge international star.
Groups on the show have traditionally not done as well as solo acts, but Simon believes JLS can match Leona’s phenomenal success.
He said: “JLS are the only group we’ve ever had on the show who had what it takes.”
