And here, because we just couldn't help ourselves, is a video of Carolina Panthers quarterback Cam Newton(notes) singing along to Justin Bieber's "Baby" at the Panini NFL Rookie Card shoot in Los Angeles over the weekend. Frankly, I'm less appalled about the ad hoc karaoke, and more disturbed by the out-of-the-box freestyle Newton tries at the end.

After all, the whole point of karaoke is to sing horrible music horribly, and Newton obliges on both counts. But the bad freestyle? That should be a matter of concern for Newton's new (well, eventually new) NFL team. Rolling a good freestyle requires the ability to process information, be imaginative, think quickly on your feet, and adjust to changing circumstances — all primary attributes for optimal quarterback play. Perhaps there should be a freestyle competition at the NFL scouting combine every year. Because between this video and Newton's strange decision to dress like Carlton Banks when he went one-on-one with Jon Gruden in Gruden's QB Camp, we may be looking at a guy who has more issues than the transition from a two-digit offense to NFL verbiage.

In any case, here's what Newton put down. Panthers fans, you may want to avert your eyes and ears (or wait for Jimmy Clausen(notes) to start singing "I Will Always Love You…")
