They won over fans with their comedic jabs at the 2016 MTV Movie Awards in April.

And clearly Dwayne ‘The Rock’ Johnson hadn’t had enough of the banter as he posted a humorous Instagram snapshot on Wednesday poking fun of his  Central Intelligence co-star.

‘Travel light my friends,’ the 44-year-old star wrote alongside a photo of himself lugging a huge bag at an airport.’Literally the biggest bag on earth but I need something to carry @kevinhart4real.’

‘Traveling light’: Dwayne ‘The Rock’ Johnson, 44, poked fun of his Central Intelligence so-star Kevin Hart with a humourous Instagram snapshot on Wednesday

Dressed in casual blue jeans, the hunky actor’s bulging biceps were on display underneath a grey T-shirt.

The 6ft 5in former WWE wrestler poked fun of his co-star Kevin Hart, 36, who stands at more than a foot shorter than his bulky fellow cast member.

In the film – which is scheduled to hit theatres June 17 – Johnson plays an overweight teen who was bullied in high school because of his weight.

Hart plays a former high school stand out athlete who now has a boring job as an accountant.

On the eve of his class reunion, he’s contacted by Johnson, who is now a top contract killer with the CIA.

The rogue spy wants his former classmate to help him bring down a plot to sell classified military secrets but it doesn’t take long for the accountant to realize he may have bitten off more than he can chew in his quest for some excitement in his life.

‘Fat Robbie’: Johnson plays an overweight teen who was bullied in high school because of his weight

Director Rawson Thurber revealed they used special effects to superimpose The Rock’s face onto Vine star Sione Kelepi’s body for his flashback ‘Fat Robbie’ scenes from high school, according to Entertainment Weekly.

Rawson told EW: ‘When I was working on the script, this light bulb went off in my head where I thought, “Of course the kid who was bullied in high school, who was a little overweight with acne scars, would transform himself into The Rock.”‘

In a process that took six months in post-production, Weta Digital, a visual effects company, used 3-D face scans, CG animation and performance capture to superimpose The Rock’s face onto Sione’s, according to the website.
