The Rock said: ‘It is Sunday, approximately 11pm, and it’s cheat meal Sunday for all of us around the world — certainly for me here.

‘And the reason why this is history in the making is because this is the very first time that I have ever tried an In-N-Out burger or In-N-Out fries, anything from In-N-Out for that matter.

‘As he began to tuck in, he continued: ‘I’ve never tried it before, so this is a first. The fries are good, so we’re off to a good start.’

He seemed to enjoy what he tasted, penning on Instagram his first impression of the food chain: ‘A #cheatmealsunday for the history books! My first time ever eating @innout.

‘A solid start with a bite of good fries as we know s***ty fries can ruin the whole experience.

‘Pared the main course with a (quite delicious) combo pour of @Teremana Blanco & @Teremana Reposado – as founder, I make up the tequila rules.’

The star added a thumbs-up emoji, before adding: ‘This cheeseburger connoisseur will now add In & Out to ‘the list. Enjoy your cheat meals, my friends.’
