I had completely forgotten that Justin Bieber was in an episode of CSI and his role was even more significant than I remember. The CSI universe has no shortage of fantastic characters, nor does the series shy away from introducing guest stars and celebrities in smaller roles to pad out the cast. CSI has had numerous guest stars over 15 seasons, sometimes feeling as though every week offered the chance to see some new A-lister playing against type.
When I was much younger, I didn’t watch too much CSI, I had to catch up long after it had aired. However, I clearly remember watching CBS in the afternoon or over the weekend and seeing the “This Week on CSI” commercial begin. I’d wait expectantly to see if I knew who this week’s cameo would be. Whether it would be a celebrity I was familiar with like Taylor Swift, or someone I was completely unaware of but now adore, like Jeffrey Tambor. When pop music sensation Justin Bieber appeared in that ad, I was taken aback.
Justin Bieber Played Serial Bomber Jason McCann In CSI
Jason McCann Had A Vendetta Against The Police





Justin Bieber appears in CSI season 11, episode 1, “Shock Waves” and season 11, episode 15, “Targets of Obsession”, as Jason McCann, a 17-year-old serial bomber. Jason and his older brother Alex are orphans who have a deep hatred for police and when a series of bombs go off, the CSI forensics teams track down Alex as the culprit, with Jason unable to be tied to the crime. Jason is removed from LVPD custody by his guardian, but in episode 15, when similar bombings occur and Jason’s guardian turns up dead, all signs point to Jason.
The CSI team tracks down Jason and his military-trained accomplice after Jason kills more people with his bombs. With his guilt all but proven, Jason decides to go out on his own terms and pulls a gun on the police, who are forced to return fire and kill the young man. Jason had murdered many people by this point, but it still feels wrong to celebrate a teenager’s death, especially one who seemed to have fallen victim to a foster care system that never really supported him or his brother.
I’ll be honest, when I first saw that Justin Bieber was going to be in CSI, I figured it would be one of those celebrity cameos that just feels totally out of place. However, in retrospect, the young man did a pretty impressive job with his time on the show. He never felt phony or above the material and his willingness to play against his cultivated, teen heartthrob personality was admirable for such a young celebrity.
I Absolutely Love Justin Bieber’s Lowkey Cameos
Bieber Is Willing To Play Even The Smallest Role In Movies And TV Shows

I absolutely love just how many random movies and TV shows Justin Bieber has popped up in over the years. I was around the same age as Justin Bieber when he came on the scene, and as a punk rock-loving tween, Bieber’s ballads weren’t exactly my tempo. However, the fact he seemed to like movies and television enough to want to appear for even just a few minutes endeared him to me over the years.
From playing himself as a blink-and-you-‘ll-miss-it alien in Men in Black III , to appearing as Canadian Superman in the little-seen short Racist Superman , to getting himself killed in the beginning of Zoolander 2 , Bieber appears to have no problem poking fun at himself.

Unlike someone like Matt Damon, whose cameos often include bigger parts that viewers won’t miss, Justin Bieber is willing to play anyone, no matter how small the part. He just likes being on sets, like CSI, it seems.
