Halsey has broken her foot.
The 23-year-old singer could see the irony in using a traditional way to wish good luck to Fifth Harmony at the Y100 Jingle Ball concert in Florida on Sunday (17.12.17), only to end up in hospital with a fractured right foot shortly afterwards.
She tweeted: "Mood is me saying "break a leg" to @FifthHarmony last night and then being in the hospital getting a foot x Ray 35 minutes later. (sic)"
And when advised by one of her followers to simply "walk it off", she clarified she'd suffered a painful break.
She replied: "I'm not sure u can "walk off" a broken foot (sic)"
Despite using crutches to get around while her foot is in a cast, Halsey was able to ditch the walking aids to join her boyfriend and collaborator G-Eazy for a performance of their track 'Him And I' on 'Good Morning America' on Tuesday (19.12.17).
And G-Eazy - whose real name is Gerald Gillum - was delighted they were able to embrace an "incredible opportunity" to perform together.
He said: "It's interesting dating your co-worker and working together with them in new ways every single time. So you know, to share this stage today was a new experience and an incredible opportunity.
"We both are pretty intense. We both are a little bit crazy. And you know, that energy that you hear in the song is the energy that was there when we were bouncing ideas off of each other. You know, as we're writing it, as we're making it, as we're putting it together.
"We're very quick. When an idea is alive, we have to go in and record it right then and there because you might miss it and that excitement of an idea coming to life is a really cool thing that we both share."
