"Watch her on Empire, you guys," Daniels told the crowd that gathered for the event. "She's coming on Empire."
Carey's appearance on the show will mark yet another reunion for her and Daniels. The two previously worked together on the films Precious, Tennessee and Lee Daniels' The Butler. The casting decision was one that many were waiting for, as Daniels helped Carey resurrect her big screen career with her stripped-down role in 2009's Precious.
The Oscar-nominated director's relationship with Carey goes all the way back to the first film he directed, 2005's Shadowboxer, where he was introduced to the singer by a mutual friend.
"I stopped everything I was doing to make sure that I was here for you, because you've always been there for me, Mariah, before Lee Daniels was Lee Daniels," Daniels said at today's Walk of Fame ceremony. "I love you with all my heart. I'm so proud of you."
Daniels went on to call out what most people were thinking.
"I thought you already had a star on the Walk of Fame," Daniels said. "You deserved one a long time ago."
