Sometimes when we interview artists, we ask you to send us in questions online or via txt.
But Rich & Kat will be backstage with JLS on Thursday and will be putting your best video questions to the boys. They'll watch your questions, answer them, and we'll film the whole thing and post it here on capitalfm.com.
Check out Rich & Kat below and send us your questions. Remember, only the greatest questions will be answered by Aston, Marvin, Oritse and JB so be creative!
