Efron has been quite the jetsetter in recent months. The actor recently joined forces with Jessica Alba, 40, to shoot tourism ads for Dubai, which offer an in-depth look into the luxurious lifestyle of the United Arab Emirates city. In a six-part promotional launch, the two will be appear in ad campaigns that imitate film trailers for genres such as spy thrillers and romcoms, ET reports.

The stars play a bickering couple who are traveling throughout Dubai’s high-end world of lavish hotels, water-front restaurants and picturesque sand dunes.

In August, Efron appeared alongside Alba in his very first TikTok. The two have racked up over 14 million views with a choreographed dancing video set to the tune of "Don’t Rush (Remixed)" by Shayan. Efron and Alba are seen busting their moves while wearing matching neutral-toned attire.

The ads are directed by Craig Gillespie and will be released over the course of the next several months.
