Extensive work: Dwayne ‘The Rock’ Johnson gave an update on the extensive work he’s having done on his bull bicep tattoo over the weekend

On Friday, Johnson shared photos to his Instagram showing him watching Yomico work on his arm.

‘Evolution of the Bull tattoo is almost complete. Day 2 and inking over 25 hours so far with my brother and hyper-realistic specialist @yomicoart in my basement.’ he wrote.

‘Yomico’s masterful in his skill and we’ve spent many months (almost a year thru Covid) collaborating on details and story that the tattoo will represent.

‘Almost done and almost time to break out the tequila’ he added.

The next day, the Baywatch star revealed he’d sat for five more hours of work on his arm.

Work in progress: The 49-year-old actor originally began enhancing the tattoo back in 2017 to cover up a smaller bull inking he’d had for over two decades

30 hours: On Friday, Johnson shared photos to his Instagram showing him watching Yomico work on his arm adding more detail and different features to the hyper realistic image

‘Evolution of the Bull tattoo is almost complete. Day 2 and inking over 25 hours so far with my brother and hyper-realistic specialist @yomicoart in my basement.’ he wrote

‘Close to 30 hrs of tattooing (pretty challenging as my whole upper arm and shoulder wasn’t a blank canvas but rather enhancing and adding to what was already there so the level of detail, precision and specific color for my skin takes a lot of time) with my brother @yomicoart.’

In 2017, Johnson debuted the large bull tattoo on his right bicep which covered up a smaller and more simple design he got done during his early pro wrestling days.

Taking to Instagram Johnson shared a side-by-side of the original bull tattoo along with the new design done by artist Nikki Hurtado.

‘Evolution of the bull begins w/ @nikkohurtado. I’ve engrained this bull in my DNA for two decades. My core. Humbly, it’s also become a symbol of strength, resilience, heart, power and defiance to so many people around the world. I got this tattoo when I was just a kid. Now I need it to reflect me as a man,’ he wrote.

The Jumanji star explained how he wanted the 3D bull to look to represent his life experiences.

On Saturday Johnson gave another update, writing: ‘Close to 30 hrs of tattooing (pretty challenging as my whole upper arm and shoulder wasn’t a blank canvas but rather enhancing and adding to what was already there so the level of detail, precision and specific color for my skin takes a lot of time) with my brother @yomicoart.’

Challenging work: The actor had the work done in his own basement which featured a bull’s skull on the wall

‘Every detail is a reflection of my own personal history,’ he wrote at the time. ‘From the cracks and heavy damage in the bone representing life’s hard lessons I’ve learned over the years. Just like scars and wrinkles – I’m so grateful to have ’em because they’re earned.’

In a separate post which included a video of Nikko starting work on Johnson’s arm, the actor wrote: ‘All my ink is a rite of passage and spiritual and the MANA (power and spirit) has to be right before we begin. Mana is strong with world renowned Nikko.

‘We talked for hours about the man I am today, compared to who I once was. And who I’ll always be. We all desire to grow and evolve. The mana is right.. let the blood and pain begin. #EvolutionOfTheBull,’ he added.

Muscle bound! Last month, Johnson, 49, showed off the results of his training during a late night gym session to prepare for scenes for upcoming film Black Adam
