Miley Cyrus can’t be stopped when it comes to trolling Shawn Mendes.

The “We Can’t Stop” singer hilariously challenged Mendes' recent Calvin Klein campaign by posting a photo of herself topless and wearing the brand’s signature underwear.

To keep the photo Internet-friendly, Cyrus covered her nipples with red hearts and did the same for Mendes' picture.

“Don’t leave your children with Miley,” Cyrus captioned the side-by-side of her topless shot with Mendes’ photo on Twitter.

Mendes sent fans and celebrities alike into a frenzy over the weekend when he announced he will be featured in a new Calvin Klein campaign, and posted two photos that showed off his washboard abs.

“@CalvinKlein #MyCalvins. Campaign coming this week,” Mendes captioned the Instagram post, which garnered more than 8 million likes as of Wednesday morning.

The sizzling shots of the 20-year-old singer caught the attention of Jennifer Lopez, Alex Rodriguez, rapper Hoodie Allen and Drake Bell.

“Killin’ it,” Lopez commented, while her boyfriend and former baseball star wrote, “Goals!!!!!” with a thumbs up emoji.
