Now that he's all grown up and much too old for trick-or-treating, Justin Bieber decided to spend his Halloween chatting with Jay Leno on The Tonight Show!

The "Baby" singer revealed to the late night host that the last time he celebrated Halloween was, "probably 14 or 15, a long time ago. I went as a clown".

The 17-year-old also dished on his favorite costume: "When I was really young my dad used to do carpentry, and I just wore his work outfit. He put me in a hard hat, drew on a mustache, and put me in overalls."

And what about that recent ticket Justin received while cruising in his "Batmobile" last Thursday?

    "I've gotten one ticket, only one ticket. I was speeding, I wasn't going too fast, but the thing was it was in a construction zone and I didn't realize, because I was right getting into the construction zone, and all of a sudden he turns on his lights and he pulls me over, and he says, 'Do you know why I pulled you over?' and I say, 'Why because you like my car? '."


Not the smartest way to get out of a ticket, Biebes!
