Justin Bieber apologizes for revealing his potentially offensive naked butt

Just as the moon rises and falls in the night sky, so has Justin Bieber’s butt risen and fallen on Instagram.

The pop star has deleted a -- what’s the opposite of full-frontal? -- vacation shot of himself naked, booty prominently exposed, and offered up an apology.

Apparently, he’s now thinking of the children.

“Hey I Deleted the photo of my butt on Instagram not because I thought it was bad but someone close to me’s daughter follows me and she was embarrassed that she saw my butt and I totally wasn’t thinking in that aspect,” he wrote Saturday, captioning a shot of himself fully clothed. “And I felt awful that she felt bad. To anyone I may have offended I’m so sorry. “

He apparently didn’t mean anything by it a week ago when he posted the bare-backside shot.

“It was completely pure hearted as a joke but didn’t take in account there are littles following me!!! Love u guys,” he said.

Meanwhile, over on Chrissy Teigen’s Instagram page, her hubby John Legend’s butt remained unapologetically visible. Different audience, it seems.
