The stars slayed on set and made the day so much fun, from their impromptu dancing to their karaoke moments (they sang along to their own cover of “Little Do You Know” between poses!) to their constant smiles and giggles.
They truly lit up the room and had so many amazing shots we could hardly pick which one to use on the cover!
Check out the behind-the-scenes video below for a look inside the shoot, and grab your copy on Tuesday!
