They’ve courted the reality TV fans, the pop fans and now the Eurovision fans, but it's only a matter of time before dance-happy club-hoppers climb aboard the good ship Jedward. 'Bad Behaviour' sees the brothers Grimes finally score a track worthy of their hero Britney Spears, and inexplicably, they’re sounding like a pair of sugared-up Justin Timberlakes (a very good thing indeed). This track, taken from their forthcoming second album, is a fierce Eurodance stomper and one that could easily slip onto the Femme Fatale record without Britney noticing.
