Mother Monster was always likely to get a tattoo tribute from one of her Little Monsters, and so Lady Gaga was inevitably going to end up on this list at some point. The style icon, singer and movie actress may have started her career being compared to Madonna, but she's arguably the person who's come closest to wrestling the 'Queen of Pop' crown from her head and surpassing her. She may have to fight Rihanna for that honor, though!
There are two clues on the tattoo that this is quite a recent image. Firstly, Gaga has her David Bowie tattoo, which she had inked in his honor after he passed away in 2016. Secondly, the number 17 next to the tattoo is a reference to her performance at the 2017 Super Bowl. If you look closely, she's also wearing an NFL t-shirt. Associating her so closely with the sport seems an odd way of paying tribute to Gaga, but she'd be the first person to tell anyone to do what feels right for them.
