When it comes to the hypothetical desert-island scenario, most of us probably imagine packing for survival and sanity. (My three desert-island essentials, for example, would likely comprise a pair of crunchy hiking shoes, a machete, and a fat, parable-filled tome à la Edith Hamilton’s Mythology or, simply, the Bible.) But if you’re Timothée Chalamet, on a pseudo-ultra-private beach getaway with his partner of three years, Kylie Jenner, those proverbial essentials take on a different utility.

In a 17-slide gallery posted to Instagram yesterday, the Dune star showed off a series of snaps from the couple’s recent trip, the itinerary of which appeared to include running on white sand, jetskiing, and, per his Instagram stories, listening to “The Chain” by Fleetwood Mac. Judging from the contents of this post, Chalamet’s desert-island musts include a dainty Prada triangle-logo chain necklace, black board shorts, and a pair of Thom Browne-branded Asics sneakers (which, by the way, debuted on the GQ Bowl runway last month). Admittedly, this trio of items would not be great for facing forces of nature alone, but Chalamet does not seem to be enjoying this beachy excursion solo.

Notably absent from Chalamet’s extensive visual broadcast was Jenner herself, who also published her own white-sand-beach vacation pics in three separate Instagram posts, one of them to the tune of the Beatles’ “Hey Jude.” (Chalamet scored his post to the relatively lesser-known Beatles song, “The Ballad of John and Yoko.”) The tandem posts introduce the notion that the two stars were taking photos of each other, and where Chalamet’s photos featured soft close-ups of his slightly sunburnt face and sneaky, playful shots of him lying on the shore, Jenner’s were rather red-hot and gaze-y. Though neither tagged the other, the starkly different posts did offer a quick study on the disparities between the male gaze and the female gaze. (Not a knock—just merely an observation.)

Since Jenner and Chalamet began their courtship, the duo has conspicuously refrained from posting one another on social media in any explicit manner. Aside from their joint red-carpet appearances, the most direct self-recognition of their union came when Chalamet accepted his Golden Globe earlier this year for his performance in Josh Safdie’s ping-pong epic Marty Supreme. During the speech, he thanked Jenner not by name but rather by referring to “his partner” as the camera panned to Jenner in the audience; she acknowledged this by mouthing the words, “I love you.”

The soft, not-so-secret roll-out of this megawatt celebrity coupling is, frankly, kinda sexy. Two of the most visible people on the planet, breadcrumbing a combined 411 million Instagram in the form of digi-cam pics and Beatles songs? Perhaps the years-old concept of the “hard launch” versus the “soft launch” has birthed a new trend: the edging false start.
