Were you there?
What we wouldn't have given to have been in the dressing rooms of Alton Towers Live this weekend. Not only were the JLS and McFly boys there, but The Saturdays popped along too! Great news for Marvin Humes and Rochelle Wiseman who will have probably stolen a few smooches - maybe a bit awkward for Frankie Sandford and Dougie Poynter?
Oh they're a colourful bunch aren't they.
Check out The Saturdays singing Notorious in this fan-made video below (love the dance moves gals!)
