Avril Lavigne performed in Brazil on Tuesday night, August 2, and was harassed on stage by a fan. 

The 'My Happy Ending' singer had just announced to the crowd that she was about to treat them to a rendition of Coldplay's 'Fix You' when a male fan ran onto the stage and attempted to grab her.

Luckily, Lavigne's fast-acting security managed to remove the man before anything happened. 

The incident was caught on camera by an audience member and Lavigne can be heard screaming in shock at the surprise addition to the stage and then telling the crowd "it's all good", before continuing with the song.
