It’s no secret that Jennifer Aniston’s fiancé Justin Theroux is a bit of a bad boy, but is he a law breaker?

On Tuesday, photos surfaced showing Theroux sticking a Velcro license plate onto the back of his motorcycle.

A removable license plate is often times used by motorcycle owners so they can avoid getting ticketed if they park illegally. A vehicle parked illegally in New York City, where Theroux was spotted, can be issued a $110 ticket.

According to X17, a car near Theroux's bike had been ticketed for parking in the area.
