Maroulis, who originated the role of Drew in the Off-Broadway premiere of Rock of Ages, was initially contracted with the Broadway production through September. The actor was nominated for a 2009 Tony Award for his performance.
"On behalf of all the producing team, we're so happy to have Constantine with us for another year to continue thrilling audiences with his incredible voice and earnest performance," said Rock of Ages producer Carl Levin in a statement.
"I am thrilled to be able to continue in my role in ROA," Maroulis added. "To be able to create a role on Broadway and get nominated for a Tony has been a dream come true. I want to thank the producers for all the support they have given me and this show."
Maroulis became a household name after becoming a finalist on the fourth season of "American Idol." He made his Broadway debut as a replacement in The Wedding Singer and followed in the Off-Broadway revival of Jacques Brel… Maroulis also appeared as Roger in the national tour of Rent. His albums include "Constantine," "Killer Queen" and "American Idol Showstoppers." A new solo album is forthcoming.
