Miley Cyrus is no stranger to controversy, but she probably didn't expect a big commotion about her latest Instagram snap.
The pop star shared a photo of her new planet tattoo with her 41 million followers, writing "lilbbjupiter".
Only some people are convinced Cyrus has got the planet's identity all wrong.
Why? Because many people are stating that Jupiter doesn't have rings.
"Uhh...that's Saturn...the only planet with rings..." one Twitter user wrote.
Sorry to break it to you guys, but Jupiter actually does have rings and Saturn isn't the only planet with them.
While Saturn's rings may be more visible than others, all the other gas giants in our solar system - Jupiter, Uranus, and Neptune - have them too.
