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.'

It's surprising the actor has time to hit the gym given the number of new projects he has on his roster.
In the new animated film DC League of Super Pets, Dwayne lends his unmistakable voice to Krypto the Super-Dog, who shares the same incredible powers as his owner Superman.
Together they fight crime in Metropolis, but he's tested like never before when Superman is kidnapped and Krypto has to save him... despite losing his own powers.
He forms a team of shelter animals who were given superpowers to help rescue Superman and the rest of the Justice League.
Johnson leads an all-star voice cast that includes his frequent collaborator Kevin Hart, Vanessa Bayer, Natasha Lyonne, Diego Luna, Marc Maron, Kate McKinnon, Keanu Reeves, Dascha Polanco, Ben Schwartz, Jemaine Clement, Daveed Diggs, Jameela Jami, Olivia Wilde and Thomas Middleditch.
Jared Stern and Sam Levine direct the animated superhero adventure, which will face the new film Vengeance in theaters plus the re-release of A24's Everything Everywhere All At Once.
Box office prognosticators have projected an opening weekend between $40 million and $60 million for the animated adventure.
