Watch Ricky's report
Like loads of you guys, here at Newsround we can't get enough of JLS.
So when we heard they would be performing and meeting fans at a very special breakfast, we just HAD to send Ricky.
Aston, Marvin, JB and Oritse met the kids at an event organised by Rays of Sunshine, a charity which grants wishes for seriously ill children in Britain.
They even belted out Everybody in Love.
