It’s Harry Styles’ Tattoo!

That "17 Black" ink belongs to One Direction member Harry Styles! Originally, when no one could catch a clear glimpse of the tat, people were saying it was Harry's audition number (165998) from 'X Factor,' the show where One Direction got their start.

However, after this photo of half-naked Harry started making its rounds on the Internet, we could clearly see that the tattoo reads "17 Black." So, what the heck does that mean?

Well, it's a reference to the James Bond films, as this is Agent 007's go-to roulette number when he's getting ready to take down bad guys in casinos. We bet like most guys, Harry is a huge fan of the series, and since he's a suave Brit just like Bond, it's a pretty appropriate and fun piece of ink.
