Rizzle Kicks have already collaborated in one form or another with Olly Murs and James Corden and can now add "generally wicked guy" Jamie Cullum to that impressive list.
Jordan and/or Harley tweeted earlier that the incredible pairing were "in the studio" together, complimenting him by saying he's "really really really good at playing the piano".
That, some might argue, is the main point of 'Cullo'. But there you go.
