The 16-year-old will have a guest appearance on the show.
Prince will play Cooper, a trauma victim who bonds with Silver (Jessica Stroup) over the realization -- at a very young age -- how precious life is. He is filming his guest spot this week, the Hollywood Reporter said.
The announcement comes just week after Prince joined Entertainment Tonigh as their on-air correspondent.
"I'm looking to become well-rounded as a producer, director, screenwriter and actor," Prince told ET's Brooke Anderson last week.
