Justin Bieber
Justin Bieber doesn't love to tell the story behind his tattoos, but this particular one has some serious significance. This tattoo is to commemorate the "king of pop" Michael Jackson. Bieber got this after Jackson's death because he was one of his all-time idols.
Brooklyn Beckham
Beckham got this tattoo on his bicep to commemorate his passion for, well, photography. This was a gift to himself for being patient and allowing his passion to drive him to higher heights than he ever dreamed of. He did not come from money, and he did not have any help on the way to the top. His work spoke for him.
