You know that feeling when you go out to a swanky club one night and end up accidentally flashing your bum to Aston from JLS? No? Well our Rio does. She was wearing her snappiest jumpsuit, complete with an out of the way (and easy to forget...) zip that runs down the back. After visiting the loo, Rio walked confidently back into the club, only to have a worried onlooker inform her that her zip was open, exposing her bottom to the entire place, including Aston, who was propping up the bar mere metres away. Mortifying.
