Sam Smith shocks fans with NSFW Instagram pic (of a woman)

Things got a little confusing on Sam Smith's Instagram last night when the singer posted a picture that seemed very out of character indeed.

Many fans believed the singer may have been hacked when he unexpectedly shared a very raunchy photo, but as the image remains on his page this morning, it appears the post was totally intentional.

The photo, showing a naked woman pressed up against a shower door, was simply captioned with a smiley face emoji. Here it is blurred out:

Sam came out as gay in May 2014, and last night fans were quick to assume the singer had not posted the photo himself. "I'm so confused," wrote one, with another adding, "Pretty sure he has been hacked." Perhaps he was just admiring the view…

The singer is not the first person to spark controversy with an NSFW Instagram post this week. Designer Marc Jacobs was left red-faced on Tuesday night when he accidentally shared a private picture on his public timeline, showing the world what he looks like naked:

As for Sam, while it's still unclear whether or not he intended to post last night's picture, the sexy snap already has 88,000 likes… not bad at all.
