In the light of the news that JLS are splitting, here's a look back at when Kev & Ros spoke to the boys themselves!
The R&B group - made up of Aston Merrygold, 25, Marvin Humes, 28, Jonathan 'JB' Gill, 26, and Oritse Williams, also 26 - shot to fame in 2008 after finishing second to Alexandra Burke on the TV reality show.
