"The X Factor" UK 2015 is entering the fourth week of Live Shows on Saturday. The remaining top seven finalists will perform live again before their coaches and audience with the hope of advancing to the next round.

Expect lots of emotions during Saturday's performance as the Live Shows week 4 is themed "Love and Heartbreak". The night also will see Ed Sheeran and Rudimental perform the song, "Lay It All on Me" together.

Unlike in the previous Live Shows where two acts were eliminated during the elimination episode based on public votes, only one will be sent home from now on until week 6. Two acts that get least votes will be made to perform again for survival.

According to reports, Cheryl Fernandez-Versini's GROUPS' 4th Impact will perform "Ain't No Other Man" by Christina Aguilera and Reggie N Bollie will render "Dangerous Love" by Fuse ODG and "Shut Up and Dance" by Walk the Moon. Nick Grimshaw's BOYS' Mason Noise will take on the song "Jealous" by Nick Jonas and Che Chesterman will sing "Yesterday" by The Beatles.

Rita Ora's GIRLS' Lauren Murray will sing the song "We Belong Together" by Mariah Carey and Louisa Johnson will take on James Bay's "Let It Go." Simon Cowell's OVERS' lone contestant Anton Stephans will render the song, "One Sweet Day" by Mariah Carey and Boyz II Men.

"The X Factor" UK Live Shows week 4 will kick off at 8pm on Saturday, 21 November. The episode will be telecast live on ITV.
