Miley Cyrus has been tapped to fill in for Mariah Carey, who canceled her upcoming "Today" show concert scheduled for August 28. Carey was set to debut tracks off her new album, Memoirs of an Imperfect Angel, during her appearance

No reason has been given for the cancellation, according to ABC 15. Cyrus most recently appeared on the Teen Choice Awards, which aired Monday, and received some flak for the provocative performance of her new single, "Party in the U.S.A."

Carey recently performed on "America's Got Talent," hosted by her husband, Nick Cannon — she sang her single "Obsessed."

Cyrus and Carey have recently been linked in another way. Cyrus will be the latest pop star to join the ranks of VH1 Divas when the concert series returns this September. Carey had been one of the original divas when the show made its debut in 1998.

"Adele, Kelly, Leona and Miley have all captured the world's attention with their talent and have earned their designation as VH1 Divas this year," the show's producer, Lee Rolontz, said, referring to the new lineup. "Don't let some of their young ages fool you — these women are among the best entertainers in the world and will continue to thrill music fans for a long time to come."
