Oops!

Katy Perry won one of the big prizes at France’s main music award ceremony – but it wasn’t meant for her.

Katy claimed the gong for Best International Song at the NRJ Awards in Cannes, for her 2008 worldwide smash ‘I Kissed A Girl’. However, the real winner was Rihanna for ‘Disturbia’. Oops.

Apparently this was all down to a mistake in the vote counting.

However Katy did win a prize, for her 2008 major label debut ‘One Of The Boys’. Well done her!
