On the set list: two songs from Bieber's platinum-selling "Under the Mistletoe" album.

X Factor fan favorite Drew Ryniewicz will see her dream come true next week when she performs on the show’s finale with her idol Justin Bieber. On the set list: two songs from his Under the Mistletoe album, which was just certified platinum marking sales of more than 1 million copies, reported to be “The Christmas Song” and “Santa Claus is Coming to Town.” The performance was taped on Dec. 14 following the broadcast. 

Stevie Wonder will also accompany the two, sources reveal to THR. On Saturday night, Bieber, along with Drake and Michael McDonald, is scheduled to appear at L.A.’s Nokia Theater for the 16th Annual Stevie Wonder House Full of Toys benefit concert.

Viewers may recall that 14-year-old Arizona native Drew auditioned for X Factor with her own unique spin on Bieber’s hit “Baby.” The performance was good enough to get her through to bootcamp.

Although she made it as far as week 6, Drew, who dropped her last name halfway through the competition, was sent home after failing to impress with “Listen to Your Heart,” a 'save me' performance even she said “sucked.” Her elimination resulted in Twitter wars and death threats aimed at judges Paula Abdul and Nicole Scherzinger, who voted to send Drew home.

While traumatic for all, Drew felt a lot better the next morning when her favorite pop star tweeted a message of support her way and joined her ever-growing legion of followers (134,000 and counting). Bieber’s words: “keep yr head up. I lost my 1st competition too. this is just the beginning. never say never.”

Indeed, for Drew, never seems to be now.

The finale airs live from the X Factor studio on Dec. 21 and 22 on Fox.
