Billie Eilish responds to a TikTok user who criticized her Oscars dress with a video of herself sitting on the toilet

• Billie Eilish attended the Oscars on Sunday wearing a black Gucci gown.
• A TikTok user criticized the look, quipping, "I've had enough of her shit."

Billie Eilish had a hilarious response to a critic on TikTok, who labeled her one of the worst-dressed celebrities at the Oscars.

Eilish attended the ceremony on Sunday wearing a black, off-the-shoulder gown designed by Gucci. True to her signature style, the look was defined by several layers of fabric and an exaggerated silhouette.

TikTok user @koltenkephart, who critiques celebrity fashion and has over 77,000 followers on the app, criticized Eilish's dress in a recent video.

"I've had enough of her shit," he quipped.

Eilish replied using TikTok's duet feature, filming herself flipping off the camera while sitting on the toilet.

"i HAVENT had enough of my shit. i am shitting right now," she wrote in the caption.

Eilish had two outfit changes later in the evening. She wore a black top and matching pants while performing the James Bond theme song "No Time to Die," for which she took home the award for best original song.

She also wore a shorter, edgier version of her red-carpet look at the Vanity Fair after-party held in Beverly Hills.
