Country superstar is special guest next week

Dolly Parton is set to appear on American Idol next week, as mentor to the finalists.

The country superstar, who recently cancelled a US tour and SXSW appearance due to back problems, will be a mentor on the April 1 airing of the show and will return April 2 to perform her single ‘Jesus & Gravity’ from her new album ‘Backwoods Barbie’, reports Perez Hilton.

As previously reported on NME.COM, Icelandic singer Hafdis Huld expressed great disappointment at Parton‘s cancellation of her live show at NME�s SXSW party at Wave in Austin, and revealed her dream to duet with Parton on �Islands In The Stream�.
