The singer was performing with her Little Mix bandmates at the Access All Eirias Festival in Wales when a member of the audience obviously thought she was in need of some refreshment and decided to throw a bottle of Sprite onto the stage.
Unfortunately for Leigh-Anne the plastic bottle hit her on the head but she recovered instantly to finish the performance of 'How Ya Doin'?'.
What a trooper!
The girls are currently in the middle of recording their second album, which Girls Aloud star Nicola Roberts recently revealed she is penning tunes for.
This makes us very excited indeed (the bottle thrower less so).
