Spare a thought for Hugh Jackman, who decided to share a sunny snap to his social media and thought nothing more of it.
The Wolverine star appeared to forget about one thing though: many of us can give the FBI a run for its money when it comes to spotting tiny details on social media.
We've all got that one friend who can figure out where someone is by some seemingly unimportant detail in a picture, or track down someone's socials without even knowing their surname.
Now Hugh's fan have done the same and everyone has been asking for more information after noticing something that might not immediately be obvious.

Earlier this year, Hollywood A-Lister Hugh revealed that he had split from his wife of 27 years, Deborra-Lee Furness.
However, eagle-eyed fans think they have spotted a reflection of a woman in Hugh's sunglasses and have been trying to figure out the identity of the mystery lady and whether she's a new love interest of The Greatest Showman icon.
"Who's the woman on your sunglasses?" asked one follower.

They weren't alone in their sneaky skills either as another confessed: "I did the very same."
One social media user praised their investigative skills, saying: "You've got good eye spy skills!"
Hugh is spending time in Australia in the run-up to the Christmas season and has been seen with his two children, Oscar, 24, and Ava, 19.
He spent time on a boat in Sydney Harbour, which is where the happy picture was taken.

It's likely that the woman pictured in the sunglasses is a friend of Hugh's or the wife of one of his friends who also joined him on the boat.
However, some fans were quick to speculate whether it was actually Sutton Foster, a Broadway star who many suspect is Hugh's new girlfriend after they first met while starring on stage together.
The rumours were shut down though after fans checked out her schedule, and confirmed she is actually in Los Angeles working on the stage production of Once Upon A Mattress.

Hugh can be seen in the pics with Michael Ryan, who is one of his close friends and personal trainer.
Another woman on the boat was revealed to be Michael's sister, and fans have been wondering if the unknown woman seen in the reflection is Michael's wife, Zoe Bingley-Pullin.
