Alex Eugene Newell was born on August 20, 1992 in Lynn, Massachusetts. He attended Kipp Lynn Academy and later the Bishop Fenwick High School, where he graduated in 2012. Growing up, Alex was a valued member of both his school's and church's choirs.
Alex's big break came as he was accepted to compete on The Glee Project casting show to win a role on the hit musical TV series Glee. Although he finished a runner-up on the show, producers of the show decided to grant him two episodes and he debuted as Wade 'Unique' Adams, a transgender student, in 2012. Fans of the show were so enamored with the character of Unique that Alex was invited back to Glee for a full-time or recurring role from the fourth season onwards. Between 2012 and 2015, Newell has appeared in a total of 43 episodes of Glee.
Since then, Alex has starred as Morgan in Resident Advisors on Hulu in 2015 and as Sam in Imaginary Friend on NBC in 2016. In February 2016, he released his debut EP called POWER.
Alex made his Broadway debut as Asaka, Mother of the Earth, in the Broadway revival of Once on This Island on November 9, 2017, and remained with the production until its final performance on January 6, 2019.
