Grimes has taken to Instagram to share that she was hospitalised after her guest appearance on Saturday Night Live over the weekend.
The episode was hosted by Grimes' boyfriend, Elon Musk, with Miley Cyrus taking the stage as musical guest.
"Forgot to post these cuz I somehow caused myself to have a panic attack and went to the hospital yesterday which tbh was quite scary and I suppose it's a good time to start therapy [sic]," she wrote alongside photos with the Wrecking Ball singer.
She went on to praise Miley, as well as Elon with whom she shares one-year-old son, X AE A-Xii.
During his SNL monologue the Tesla and SpaceX entrepreneur joked about his son's much-talked-about name, saying it's pronounced like a "cat running across the keyboard".
