The "Morbius" star made a statement, carrying a replica of his decapitated head as an accessory during Monday's fashion event, and stars couldn't resist spewing some NSFW jokes.
Zach Braff took the cake, causing the most laughs with his response to a post written by CNN's Derek Blasberg.
The style correspondent shared a picture from inside the Met with Leto, captioning the shot, "Does this mean I can tell people I had a threesome with @jaredleto?" Brauff responded, "Derek let me write these for you: 'Jared giving me head.'”
Fans couldn't resist taking a shot about penning their own dirty jokes on Leto's outfit.
"Jared gave me head, twice in one night," one person wrote. "If I'm not mistaken he gave Shawn Mendes 'head' first, sloppy seconds = Eskimo brothers," commented another.
FYI - Leto was passing his head around all night, and the first lucky recipient on the red carpet did happen to be Shawn Mendes.
