WHO knew filming James Corden’s Carpool Karaoke could be so dangerous?

Ariana Grande took to social media on Wednesday to share that she injured her hand while filming the popular series.

“Well Mr. Corden, today is off to a wild start,” the 25-year-old said in an Instagram story in which she showed off her left hand bandaged with gauze. She captioned the image “Bleeding n smiling.”

She captioned another image, “Hahahahahaha I’m an idiot.”

While it’s unclear what exactly happened, Grande didn’t let that stand in the way of her fun.

“That was the best day ever @JKCorden thank you so much to you and your incredible crew and band and writer! Sm fun. Can’t wait for y’all to seeee what we been up to,” she tweeted.

Presumably, she was on the show to promote her new album, Sweetener, out later this month.

Perhaps fans will see the injury first-hand when the episode airs.
