Everyone's doing it!
And Justin Bieber is the latest celeb to let his tongue hang loose!
It certainly can't rival Miley Cyrus' long licker, but good for the Biebs to not be afraid to show what he's working with even if he measures up a little short compared to others.
While playing basketball in Hollywood with Lil Za And Lil Twist - who are apparently still in the pic if not in the house - the Biebs rocked his lil tongue all about the court as he tossed up some hoops.
But we sure hope he was careful on that court because we hear the Biebs has to walk in with Floyd Mayweather Jr. for his big fight tonight!
And just a note: we're guessing Floyd doesn't want that tongue out and about during the intro, so tuck it away!
