If looks could kill: Caitlyn Jenner breaks red carpet etiquette at Mel Gibson premiere
The general rule on the red carpet is - everyone gets their turn.
But Caitlyn Jenner wasn't waiting for anyone, even the director of the film which premiered.
Jenner hit the red carpet at the world premiere of Hacksaw Ridge in Los Angles this week and walked right in front of director Mel Gibson, who was posing with his partner Rosalind Ross.
The 66-year-old Olympic gold medallist is no stranger to red carpet decorum, having attended a number of exclusive events for the last 40 years, which dictates that each celebrity poses at the designated spot in front of photographers for a reasonable amount of time before moving on and allowing the next to take their turn.
And she didn't look too happy about being stuck behind Gibson if that side eye is anything to go by.
It looked like the awkwardness didn't last for long though as the pair were later pictured chatting together inside the event.
That's Hollywood for you.
