Earlier in the day, Ruby took to Instagram to share a celebratory video of herself and her new film's leading man Vin Diesel together on her first day of filming the action flick reboot.

The 12-second video - originally shared on the app by the American stunts-man - starts off with Vin talking to the hand held camera with Ruby in the background of the shot. 

He says with a cushion wrapped around his neck: 'So her first day of filming - the amazing Ruby Rose playing Adele. She's a monster.'

The camera then moves to focus on the DJ who is dangling mid-air with the aid of a harness. 

Ruby, who will play a sniper named Adele in the upcoming movie, then says: 'I've just been hanging in a tree for like four hours. No big deal. I love how you come and grab me at my worst angle.'
