Dominic Purcell has shared a rare photo of his son Joe.

Taking to Instagram, the Australian Prison Break star posted a snap of Joe, 24, enjoying a cigarette.

Joe has clearly inherited his father’s good genes, looking handsome in a black sweater over a white top as he looked at his iPhone.

He accessorised with a stylish ring and black nail polish.

Dominic revealed his son is following in his footsteps, writing in the caption that he was preparing for an audition.

‘Joe Purcell lookin very #kurtcobain for an audition. Ummmmm painted nails not my thing son, but I am a fuckin fossil haha. …..Kids these days,’ he wrote.

Earlier this month, he also shared a touching tribute to his eldest child on Instagram alongside a photo of the pair embracing.

‘Joe Purcell Jr. When ya sons grow up and become ya best friends. A Dads dream. They don’t take any crap from the old man ha!…Then ya you know you’ve done your job,’ he wrote.

Dominic shares Joe with his ex-wife Rebecca Williamson, who he split with in 2008.

They are also parents to daughter Audrey, 23, and twins Lily-Rose and Augustus, both 21.

The children are step-siblings to pop icon Miley Cyrus following Dominic’s marriage to Tish Cyrus in 2023.

Dominic began dating Tish , 57, in July 2022 — which was just three months after she divorced Billy Ray Cyrus.

Tish revealed her and Dominic’s engagement news in April of 2023 by sharing a pair of loved-up pictures that showed off her diamond sparkler.

The newlyweds wed in an intimate ceremony in Malibu, California, just four months after announcing their engagement.

The lovebirds initially sparked romance rumours after she left a string of heart emojis on his Instagram and wrote, ‘Hi Babe’ in response to one of his posts.

Tish and her ex-husband Billy Ray, 61, tied the knot in 1993 and called it quits twice before finally going through with their divorce in 2022.

The former couple share five children, Miley, 31, Trace 35, Brandi, 37, Braison,30, and Noah, 24.
