Former X Factor judge Demi shared a snap on Twitter showing Perrie Edwards, Jesy Nelson, Jade Thirlwall and Leigh-Anne Pinnock blissfully unaware of the icy intruder standing just behind them on stage in St. Paul, Minnesota.
Demi added the caption: "Tonight's prank for Little Mix's last show on the 'Neon Lights Tour'. Hehe. Love you girls!!!"
A YouTube video posted by a fan shows the cheeky snowman casually sauntering on to the stage while Little Mix perform 'Salute' and then joining them for a few dance moves. Kudos to the girls for not blinking an eyelid!
Now, some fans have suggested this snowman was actually Demi in disguise. She hasn't confirmed it yet but we like to think it was.
Little Mix have been supporting Demi since her 'Neon Lights Tour' kicked off in February, but last night marked their final appearance. "St. Paul! You guys were amazing!" tweeted Leigh-Anne. "That was a beautiful send-off for our last US show!"
