Updated: 

Drama ensues on tonight's episode of The X Factor when a particularly desperate hopeful breaks into another act's audition to sing for the judges.

Kirsty Murphy, a 21-year-old dance teacher, barges in on a girl group amid fears she will not get her chance on the final day of auditions, but judge Simon Cowell admits he likes her "sheer determination" and that she has "balls" for pulling the stunt.

She attempts to win over Simon and his fellow judges Nicole Scherzinger, Louis Walsh and Sharon Osbourne with a rendition of Alicia Keys' If I Ain't Got You.

Other acts hoping to woo the panel as auditions come to a close are a TV actor, a woman with a penchant for cockatoos and a former MOBO Award nominee who lost out to Adele.

Will Rush, 21, previously appeared on BBC drama series Waterloo Road but now has a desire to work in the music industry.

He gets out his guitar to perform a pared-back version of Zara Larsson's Lush Life for his attempt to prove he has the X Factor.

There's much laughter when Cori Burns, 63, rolls into the studio on her scooter adorned with cockatoos after admitting her goal in life is to have a number one album of her own songs.

The judges are impressed to meet Mike Hough, a 25-year-old singer from Essex who has previously scored a minor success after being nominated in 2011 in the R&B/Soul category.

He does his best to get to the next stage of the singing competition by showing off a unique version of Alanis Morissette's 1990s hit Ironic.

Other wannabes giving it a final shot before Bootcamp include a four-piece girl group, an American musician about whom Nicole declares a wish to "hit in the face" and a teenager whose parents have remortgaged their house twice to fund her dream of being famous.

The Bootcamp stage of The X Factor commences on Sunday night's episode, and will see more than 120 singers put through their paces over one of the toughest weekends of their lives in order to progress.
