Suicide Squad star Jared Leto stunned fans on Monday night (07Nov16) by posting a video appearing to show his severed fingers on Snapchat.
In the footage, the actor and rocker's pinky and ring fingers are bandaged - and appear to be missing.
The Oscar winner simply wrote: "My fingers missing."
The video sparked concern among the Thirty Seconds to Mars singer's fans, with one tweeting: "What... happened to your fingers i'm actually really worried @JaredLeto", while another added: "is @JaredLeto okay? what happened to his fingers? i'm genuinely concerned."
One devotee suggested the video was just a ruse for a new movie role, but there has been no further statement explaining Leto's possible prank.
The actor has become known as an extreme Hollywood practical joker - while playing The Joker in Suicide Squad, he really got into character and sent castmates a range of weird and disgusting gifts, including rats, used condoms, and sex toys.
If the Snapchat footage is early promotion for a new film, it could suggest Leto's new character in the Blade Runner sequel will be missing fingers. The details of his role are being kept under wraps, but he will join the likes of star Ryan Gosling, Robin Wright, Ana de Armas, and Mackenzie Davis in the reboot, which also features Harrison Ford reprising his robot hunter character Rick Deckard from the 1982 original.
Plot details also remain scarce, but reports suggest Blade Runner 2 will be set several decades after the conclusion of the original movie. Director Denis Villeneuve's sequel is slated for an October, 2017 release.
