Glam Essex singer, Rylan Clark, left The X Factor tonight (November 25).

Boy band, Union J and Clark were left head to head in the Sing Off in tonight's X Factor Results show, as the other acts, James Arthur, Christopher Maloney, Jahmene Douglas, made it through on the public vote.

In The Sing Off, Nicole Scherzinger's act, Rylan, sang Athlete's 'Wire'. Whilst Louis Walsh's act, Union J, sang Snow Patrol's 'Run'.

The Sing Off followed yesterday's (November 24) 'ABBA versus Motown' theme.

The show started with The X Factor Final Five singing Coldplay's 'If I Ruled The World'. Other performances came from Bruno Mars and Rihanna.

Aviator shade-wearing Bruno Mars sang his new single 'Locked Out of Heaven'.

Rihanna performed the UK exclusive of her new single, 'Diamonds'.  Show host, Dermot O'Leary quipped about the "British weather content" onstage after she got drenched by rain whilst singing.

Tulisa sent Rylan home. Scherzinger supported her act by sending Union J home. Louis Walsh sent Rylan home. Gary Barlow unsurprisingly sent Clark home.
