WENN
If we never see Miley Cyrus with her tongue out again it'll be too soon, but she's not the only celeb who can't seem to keep it in her mouth.
Repeat offenders - including Cara Delevingne, Rihanna and Harry Styles - love nothing more than getting theirs out in public for a good airing.
And no, we have no idea why either.
Honestly - put 'em away!
