Pulling his classic Blue Steel look from behind the wheel of the car, Ben's new cast mate is in the passenger seat, sporting a disgruntled expression.
The picture confirms rumours that Derek's son - who was seen as a baby at the end of the 2001 comedy - has grown up to be the polar opposite of his shallow father.
Arnold, who has until now had small parts including a guest role on Sam & Cat, excitedly posted on his official Facebook page last week: "Tomorrow is the BIG DAY! I'm off to Rome for 3 months to shoot a 'big studio comedy'."
No doubt veteran actor Stiller is making him feel perfectly at home on set of the film, which he is both directing and starring in.
Owen Wilson is also reprising his role as Derek's rival-turned-pal Hansel in the Justin Theroux-penned movie.
Zoolander 2 will see Derek and Hansel modelling again when an opposing company attempts to take them out from the business, but further details of the plot are being kept under wraps.
Wilson and Stiller announced the movie in typically hilarious manner, strutting the catwalk as models at the Valentino show during Paris Fashion Week on March 10.
The two actors have also posted selfies in character in front of the Eiffel Tower in Paris and in Rome.
E! Online reported that supermodel Karlie Kloss, who announced her departure from Victoria's Secret last month, will make her acting debut in the sequel after fellow model Gigi Hadid turned the role down.
Stiller's wife Christine Taylor will return as love interest Matilda Jeffries, and Will Ferrell will be back as nefarious designer Mugatu.
Zoolander 2 will hit cinemas in the US and UK on February 12, 2016.
