Sent packing: Cher Lloyd was given the boot from the X Factor last night in the first part of the weekend's final showdown, seen here being consoled by host Dermot O'Leary and mentor Cheryl Cole
After coming in the bottom two twice during the contest, she knew her chances of winning were slim.
And last night Cher Lloyd saw her X Factor dream come to an end as she was sent packing in the first part of the weekend's final showdown.
The 17-year-old hopeful from Malvern, Worcestershire, was the bookie's favourite to face the chop tonight and, predictably, received the least number of viewer votes, sealing her fate.

However, despite her disappointment, the teenager is still on course to get a record contract.
Her mentor Cheryl Cole has described her as the 'future generation of music' while Simon Cowell is also a big fan.

Later Christina performed the song Express from her new film Burlesque, which she is currently promoting across Europe, but raised temperatures as she cavorted around the stage in her lingerie and put on a provocative pre-watershed display with her army of scantily clad female dancers.
