Cher Lloyd will be giving it some attitude with Will.i.am

No-one can forget Alexandra Burke's show-stopping performance alongside Beyonce Knowles in 2008's X Factor final.
This year rapper Cher Lloyd, 17, will be joined on stage by mentor Cheryl Cole's best mate Will.i.am, for what she believes will be her final performance.
'I'm going to go out with a bang,' promised Cher at yesterday's X Factor press conference.
'I've got Mr Will.i.am with me so I'm going to rock it out.'
Will.i.am, who has supported Cheryl's mini-me Cher to win from the start, also took to The X Factor stage just last week with The Black Eyed Peas.
Another returning guest is Barbados beauty Rihanna who will sing alongside favourite Matt Cardle to help him try to secure the title of X Factor winner 2010.
Robbie Williams will be ditching his manband Take That for the evening in favour of Simon Cowell's boyband One Direction, and ultimate American diva Christina Aguelira will duet with Rebecca Ferguson.
