Jennifer Lopez fans were concerned for her safety after spotting something off in the background of her latest workout selfie.
The 50-year-old superstar posted a snap from the home gym in her Miami mansion, showing her toned physique in a camouflage print two piece.
She used a motivational quote as the headline, writing: "If it doesn’t challenge you, it doesn’t change you…"
And while many fans took to the comments section to compliment her incredible figure, others spotted something rather off.
People pointed out a "scary" figure in the background, and sure enough if you look very, very closely you can see a man looking through the window.
Can you spot him?
It's possible that the mystery man Jennifer captured a picture of was her fiancé Alex Rodriguez or perhaps someone else she was working out with, but no details have been confirmed.
Some fans thought the figure looked as if he was wearing a mask just below his nose.
But others said it looked like someone's fingers were covering his mouth.
Although some people were genuinely concerned about the "scary guy" others joked that the singer had kidnapped the man.
With one person saying: "Who's that guy tied up in the back."
Another fan said: 'Why is there a man in the background with a hand over his mouth?"
A third then added: "What's that over her right shoulder??"
Someone else commented: "So are we not going to talk about the person behind her holding his mouth."
And: "The guy in the background is scary" said a fifth.
