shared a cute photo from the Sydney set of Thor: Love and Thunder on Tuesday – yet his brother was distracted by one element of the snap.
In the image, the actor, 37, was holding hands with his little boy, who was wearing a Superman cape however his Luke could not help ribbing his sibling.
Luke pointed out Chris’ slim legs as he penned: ‘Bro?! You’ve been skipping leg days again?!’ before mocking his personal trainer Luke Zocchi.
Chris was showing off his hulking, muscular body in a vest top, while baring his legs in a pair of shorts and donned trainers.
‘Bro?! You’ve been skipping leg days again?!’ his brother Luke commented under the image, then ribbing Chris’ personal trainer, Luke.
Luke added jokingly, ‘Are those @zocobodypro’s pins?
Deciding to ignore his brother, he instead spoke of his son’s superhero preferences.
In the caption for the image, Chris admitted his son’s allegiance lies with DC’s Superman, not Marvel’s Thor, who Chris plays in the film franchise.
‘Holding my little man’s hand and asking him the age-old question: ”What do you want to be when you grow up?” Chris wrote on Instagram.
His son’s reply: “‘Dad I wanna be Superman!” ‘Lucky I have two other kids,’ the Aussie actor joked in reference to the betrayal.
It is not the first time Luke has mocked Chris, as he recently took to social media to respond to Chris’ teaser of his latest endeavor.
Chris is taking part in a new learn-to-meditate series for Centr, his digital health and fitness program, on Instagram. The behind-the-scenes video gave a snipped of him recording a guided meditation.
Luke was less than impressed however, as he said: ‘This is not relaxing me. I want my money back.’
