Nick Cannon is not the only one excited to see his wife Mariah Carey perform on America's Got Talent Wednesday night.
"I see paparazzi pictures of them all over the place, but very rarely do you see them interact together," executive producer Jason Raff tells PEOPLE of Carey's performance Wednesday on the live results show. "I have a lot of anticipation to see her perform, but also to see her interact with Nick."
As for Cannon, "He's really excited to share his primetime show with his wife," Raff says. "He's always so proud of her. He always talks about her."
Cannon, 28, is in the middle of his first season hosting AGT while Carey is promoting her new single, "Obsessed," off her upcoming album Memoirs of an Imperfect Angel.
"The fact that they live in the same house certainly doesn't hurt the situation," Raff says of booking Carey for the show. "But it's about the timing ... It's never something that we talked to Nick directly about. It's never like, ‘Do you think you can ask your wife if she doesn't mind coming on to perform?' We went through our normal channels."
In short: "She was thrilled to do it," Raff says.
Could America be witnessing the second coming of Sonny and Cher with Cannon and Carery? "They can be the first family of variety," Raff jokes. --Nicholas White
