. Before that, however, it will surely be the thrill of a lifetime for the seven remaining Idols, as they will be mentored by Mariah for their performances on Tuesday.

The success of Mariah's current album puts her in an unbelievable position to exceed one of music's all-time greats on the music charts, and to possibly pass another in the very near future. With her current single, "Touch My Body," already having reached #1 on the Billboard Hot 100 (becoming her 18th career #1 hit), she has surpassed the most enduring chart record in Billboard Hot 100 history--Elvis Presley's 17 #1's! Mariah is now positioned as the only active recording artist in the 50 years of the Hot 100 with the potential to surpass The Beatles' all-time high of 20 #1 hits!

Find out for yourself how great Mariah Carey's new album, E=MC2, is--it's available in stores and on iTunes, starting April 15th!
