"Her team wants it on the show," a source close to Carey toldUs Weekly, adding that Packer would "go along" with the on-air nuptials because "he does what Mariah wants."
Although a date hasn't been set yet for the wedding, The New York Times recently reported the wedding will take place this spring and air later this year on Mariah's World.
Mariah's World is currently filming and will feature behind-the-scenes footage of her Las Vegas residency and two-month European tour.
Carey, 46, previously served on American Idol's judging panel with Keith Urban, Nicki Minaj and Randy Jackson for Season 12 back in 2013. However, Carey called her gig the "worst experience of [her] life" and the show "fake" and "boring." The diva also feuded with Minaj basically the entire time on the set.
Carey and Packer, a 48-year-old Australian billionaire, got engaged in January after America's Got Talent host Nick Cannonfiled for divorce from her in December 2014. Carey and Cannon have four-year-old twins together named Monroe and Morrocan.
