Grimes is opening up about a "scary" panic attack that led to a recent hospitalization.

On Tuesday, the "Delete Forever" singer, 33, revealed that she suffered a panic attack shortly after making a guest appearance on Saturday Night Live over the weekend.

Sharing backstage photos of herself posting with Miley Cyrus, who was the musical guest on Saturday's episode, Grimes (born Claire Boucher) wrote on her Instagram, "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 😑😑😑."

"But nonetheless - wowwwww @mileycyrus is good live and so chill!" she continued.

"So grateful to the SNL team for being so kind and letting me sneak in as princess peach," she wrote, adding, "so proud of my beautiful E (which I know will upset the grimes fans so I apologize in advance) but he killed it."

Grimes and Musk, 49, made their debut as a couple at the 2018 Met Gala. The pair welcomed son X AE A-Xii on May 4, 2020.

Musk referenced their 12-month-old child's unique moniker during the Saturday's SNL episode, joking in his monologue that it's pronounced like a "cat running across the keyboard."

Last fall, Grimes revealed that their son already has a passion for "radical art."

"I've watched Apocalypse Now and stuff with my baby," she said during an interview with The New York Times.

"He's into radical art," the songstress added. "Like, he just actually is, and I don't think it's problematic to engage with them on that level."
