London, Nov 19 (ANI): Susan Boyle will not be crooning live on this weekend's The X Factor.

Boyle will record her song on Saturday, a day before the results show, reports the Sun.

The Scottish singing sensation's move comes after songbird Mariah Carey pre-recorded her number last weekend due to a busy schedule.

Boyle will now plug her new album in the US instead of performing at the X factor.

She is all set to wow audiences at The Rockefeller Centre in New York early Monday morning.

Meanwhile, Rihanna and Alicia Keys have been signed to sing at The X Factor on November 29.

Some of the other stars adding glamour to the show are Robbie Williams, Whitney Houston, The Black Eyed Peas, Shakira, Michael Buble and Queen's Brian May and Roger Taylor. (ANI)
