'Mum wasn't thrilled': Jack Osbourne shares snap of GIANT Samurai-inspired back tattoo that 'most people don't know about'

His father Ozzy is a heavy metal icon who has rocked tattoos for decades.

And on Saturday TV presenter Jack Osbourne suggested there is a genetic link to all that ink as he shared a photo of a massive back tattoo that depicts a Samurai warrior doing battle with a sea serpent while surrounded by mermaids and flowers.

'Here's something that most people don't know about me,' he wrote in the caption. 'Safe to say Mum wasn't thrilled at first #tattoos #backpiece."

The image divided Jack's 238,000 Instagram followers, with many saying they understand why his mother Sharon was shocked and dismayed.

One user wrote that 'it looks f**king awful,' while another added: 'Your mum should beat your a**'.  

Others applauded the father-of-two for using his body as a canvas, with one fan writing, 'that's hot jack'.

Although Jack only recently unveiled his back tattoo, it's thought he has had it, or parts of it, for several years.

Tattoos on his arms and torsos frequently appear in photos, and include the phrases Savage Times (right pectoral) and Fucking Awesome (left pectoral). 

In November he shared an Instagram photo of a new arm tattoo that depicts a mermaid with the name Pearl emblazoned across her fin.

It honours his four-year-old daughter Pearl Clementine, who he shares with his wife Lisa Stelly.

The couple welcomed a second little girl - Andy Rose - into the world last July.   

Jack's father Ozzy, now 67, kicked off his tattoo habit when he was a teenager, inking up his left arm with a dagger when he was just 15 years old.
