As it turns out, Jacob is actually much closer in age to his Glee character than almost any of his co-stars. The New York native turned 20 years old on October 17, which means that he began his Glee role when he was still only 19.
Jacob’s co-stars Alex Newell (Unique) and Blake Jenner(Ryder) are also 20 years old, making them the youngest core cast members. All three of them were born in 1992 — the same year that co-star Cory Monteith turned 10 years old. Crazy thought, no?
