Seems like it’s the week for baring it all on Instagram!

Just one day after Bieber dropped his pants in a vacation pic, Chrissy Teigen took to the social media site to post a shot of her hubby John Legend’s bare backside.

Legend is turned away in the pic, and it appears as if he has no idea that his wife is snapping the shot. But Teigen’s caption provides some insight to the seemingly random intimate pic.

The model and "Lip Sync Battle" co-host seems to be sending a message by tagging the official Instagram account on the pic, bringing to mind her ongoing, Chelsea Handler-esque battle with the social media site over the removal of topless pictures she posted from a W Magazine photoshoot.

"The nipple has been temporarily silenced but she will be back, oh yes, she will be back," Teigen promised on Twitter last week after Instagram continued to remove her shots that featured the model’s exposed nipples, which violates the site’s community guidelines.
