Miley Cyrus fans invited to a mystery event at the Chateau Marmont hotel in LA last week got much more than they were expecting.

Convened by TikTok, the event was an album-listening party AND a live performance from Cyrus herself. Which, of course, has generated a blizzard of excitable posts on TikTok and other social apps from the attendees.

Held to promote the new ‘Something Beautiful’ album, the event has been followed up by TikTok’s now-familiar in-app activation for Cyrus, with challenges for fans to unlock a branded profile frame.

There’s also a twist: a “first-of-its-kind fashion section” for the in-app hub, with videos of Cyrus talking about the clobber she wore for previous albums.

Cyrus herself has 18.7 million followers on TikTok, with the company saying that her ‘Flowers’ hit has been used in more than 5.8m creator videos on the platform.
