If there's one person you don't want to cross, it's Elton John.

'Rocketman' may have portrayed the music icon as a flawed-but-mostly-kinda-cuddly type of guy, but this footage from a recent gig in Australia shows just what kind of temper he has.

In fairness, however, he was sticking up for one of his fans.

John saw a woman being manhandled rather roughly during a gig in Perth on Sunday night, as security escorted her off the premises for unknown reasons. While between songs, he said: "Hey, you two security guards with the girl, f**k off."

In the video which was uploaded to social media, he continues: "Let her up here immediately … come on, you c**ts. Morons, both of you, morons. You don’t treat girls like that. Leave her alone, you turds!"

He reportedly later apologised for the outburst, saying that he "couldn't stand violence against women."

G'wan, Elton.
