Ariana Grande unintentionally freed the nipple while petting a pup — and then she unknowingly posted a picture of the moment on her Instagram.

The image in question features Grande crouched on the ground while sucking a lollipop and loving a happy black dog. As she leaned forward, though, her dress, a loose red gingham number, slipped down just far enough to reveal most of her boob. She captioned the carousel of photos with a series of red and white emojis, then reposted the dog pic it to her stories, apparently unaware of the wardrobe malfunction.

The photo has since been deleted.

The “We Can’t be Friends” singer seemingly responded to the snafu on Instagram stories with a throwback clip of her and her best friend, Elizabeth Gillies. The duo has made a tradition out of dressing up together or Halloween, including in 2023, when they went as Cristal Connors and Nomi Malone from “Showgirls.” They also recreated a scene from the 1995 film, which was reposted by Grande on Wednesday.

“You have great t–s, they’re really beautiful,” says Gillies as Connors.

Grande then responds in character with a sweet “Thank you.”

The “thank u, next” singer shared the image as part of a dump amid her Eternal Sunshine tour, which kicked off earlier this month at the Oakland Arena in Oakland, Calif. Around the same time, news of her split with her “Wicked” co-star, Ethan Slater, had been making headlines. They met on set — both of them married at the time —of the musical movie and dated for about three years.

Days later, she broke down in tears during a stop in Los Angeles.

“This is so overwhelming in the most beautiful way ever,” she told her cheering fans.
