Not that there was much worry on the subject, but Panthers fans can rest assured that their franchise quarterback definitely won't be boring off the field.

Cam Newton was out west at the Panini NFL Rookie card shoot in Los Angeles this past weekend, and he took the opportunity to belt out a little Justin Bieber.

Newton recognized that he may not have been hitting all of the Bieber notes, repeatedly asking if he could be autotuned. Thereafter, he followed up that performance with a freestyle to the Ying Yang Twins' "Whistle Song," in which he boasted about being the first-overall pick.
