So CSI has a new promo all about teen pop sensation Justin Bieber who is making his acting debut during their 10th season premiere on September 23rd. I have to admit whoever decided to cast him and actually got the hottest 16 year old in the world to do the part was f*cking brilliant because it is getting me to watch the show for the first time in years! You can’t tell if he got the acting chops from this promo, but does it really matter?
