Justin Bieber joined the mile high club--but not that one!

Home boy had the word "Forgive" tattooed on him during a flight to Canada five days after his DUI arrest!

I'm guessing it might've hurt a little more than usual. Bang Bang, the tattoo artist, told TMZ he worked on the tat during really bad turbulence!

The FAA said it's not illegal to get a tattoo done on a plane as long passengers and crew are safe.

Nice work, Biebs. you did something weird but at least it's LEGAL.
