Miley Cyrus to Serve as Mentor to American Idol Aspirants, Perform on Results Show This Week

She might hate the Internet, her own hit Disney show and the entire country music genre, but Miley Cyrus still has plenty of passion and expertise to go around.

The teen queen will be the celebrity mentor on American Idol this week, Fox confirms. Tuesday night will reportedly feature a Billboard No. 1 hits-themed show.

Of the 11 contestants left, three are teens: last week's sensation Siobhan Magnus, 19, Aaron Kelly, 16, and Katie Stevens, 17. Tim Urban is just 20 years old.

Of course, the three teens all took on The Rolling Stones - more than triple their age - and pleased the judges with their homages to the rock gods last week.

Will Miley be able to steer them in the right direction this week? Or will the girlfriend of Liam Hemsworth act like she's better than them? We'll soon find out ...

Miley Cyrus is promoting The Last Song this week. No doubt there will be a plug - or maybe even a track - or two from that tear-jerker when she comes to American Idol.

On Wednesday’s results show, Miley will be back to perform her hit song, “When I Look At You,” while new couple Joe Jonas and Demi Lovato will duet on “Make A Wave.”

In other words, clear the space on your DVR now, because this watershed moment in teen music history may be one you hold onto and savor for many years to come.
