Josh Krajcik, Alicia Keys to perform on 'X Factor' this week

A season one-finalist will return to “X Factor,” along with a big name singer.

Josh Krajcik and Alicia Keys will perform on next week’s elimination episode of the Fox singing competition.

Krajcik will perform his new single “one Thing She’ll Never Know,” which will be released next spring. The Ohio native, who was in the top two last year, has been working on his debut album all year. Eg White (Adele, Pink, Florence and the Machine), Stephen Kipner (Christina Aguilera), Chris Seefried (Lana Del Ray) and Steve Robson (Lily Allen, Rascal Flatts) are producing tracks for the album.

Keys is expected to play something off her new RCA Records album “Girl on Fire,” which drops Tuesday. The album, which features appearances by Babyface, Maxwell and Bruno Mars, is the 14-time Grammy winner’s fifth. Her first album sold over 12 million copies worldwide, and she was the best-selling new artist and best-selling R&B artist of 2001. In total, she has sold over 35 million albums and 30 million singles worldwide, and is one of the best-selling artists ever in contemporary music.

The remaining top eight vocalists will perform Wednesday on “X Factor,” and the elimination episode will be on Thursday.
