Turns out Katy Perry gets VERY SHOUTY when she's in a radio studio. Someone definitely had their Wheetabix this morning.
This time she was shouting for good reason though as she discovered for the first time what the "zig-a-zig-ah" in the Spice Girls' 'Wannabe' stood for direct from the source.
Perry was a guest on the UK's Heart FM with breakfast hosts Spice Girl Emma Bunton and Jamie Theakston this morning and took part in a game of 'Guess The Next Lyric' and when it came round to 'Wannabe', Perry became very enthused.
"What does it mean?" Perry shouted after guessing 'zig-a-zig-ah' correctly, to which Bunton replied, "It means... it's rude!"
This appears to have shocked Perry, who never seems to have copped on to the song before, with Baby Spice having to explain further that "it can mean anything you want it to mean... but it's rude."
