"W/ global success of "#Beautiful" (#1 in 30+ countries so far) @MariahCarey confirms world tour & says goodbye 2 Idol," Carey's camp tweeted.

"The rest of this year is jam-packed with Mariah putting the finishing touches on her much anticipated forthcoming album, headlining the Macy's 4th of July Fireworks Spectacular and appearing in Lee Daniels' [film] 'The Butler,' opening in August," her publicist told People.com in a statement.
