As this year's X Factor finalists gear up for what will possibly be the biggest weekend of their lives, what do you really know about them?

Amelia Lily, Marcus Collins and Little Mix are the remaining contestants in this series of the popular ITV talent show and the battle lines have now been clearly drawn.

After surviving the scandals, the tantrums and the sensational axing of Frankie Cocozza, all three acts are now at the final hurdle that stands between them and their goal of realising their dream to become the next Matt Cardle or, if they are really lucky, the next Leona Lewis.

The final three acts will have to raise their game this weekend as they go neck and neck for the coveted title of X Factor 2011 winner.

With three songs to work with and some surprise duets on their side, it really will be hard to call it this year.

Little Mix, the girl group put together by Tulisa are currently the bookies favourite to win the show after successfully breaking the curse of the girl groups and reaching the final. While 'comeback kid' Amelia Lily has some pretty good luck on her side following her return to the show to replace axed bad boy Frankie Cocozza. However, Marcus has been celebrated for being the most consistent act so he could also easily walk away as the winner.

Who will win? Nobody knows. But while you decide who you will be supporting this weekend lets get to know the remaining contestants a little better.

Amelia Lily

'Comeback kid' Amelia Lily was booted off the X Factor on the first live show when her mentor, Kelly Rowland was forced to sacrifice an act.

But just weeks later she was voted back onto the show after wannabe bad boy Frankie Cocozza was exiled amid drug allegations.

The 17-year-old X Factor hopeful from Middlesbrough has worked hard since her return. Her powerful vocals have saved her from getting the chop after finding herself in the bottom two twice.

Despite originally having her blonde locks dyed pink when the contestants had a makeover for the show, the singer has slowly but surely gone back to her blonde roots.

The ambitious teenager recently gushed that wants to become like Kelly Rowland and return to the X Factor as a guest star in years to come.

Marcus Collins

Marcus Collins is the final male singer in the competition. The 23-year-old singer has gained a huge fanbase since the beginning of the X Factor.

Former X Factor star Rebecca Ferguson has openly declared that she wants fellow Liverpudlian Marcus to win the show.

Throughout the series the judges have praised him for his consistency and versatility during his live performances. He has never been in the bottom two.

Marcus reportedly formed a close bromance with fellow contestant Craig Colten. He showed his more vulnerable side when he broke down in tears after hearing the news that Craig was leaving the show.

The former hairdresser says that his favourite food is Jerk chicken, rice & peas and salt fish fritter.

Little Mix

The girl group is made up of originally solo singers Jesy Nelson, 20, Perrie Edwards, 18, Leigh-Anne Pinnock 19 and Jade Thirlwall,18.

All the girls come from different backgrounds. Whilst Essex girl Jesy works as a barmaid, High Wycombe born Leigh is a waitress, Perrie and Jade are students from Newcastle upon Tyne.

The girls were put together by mentor Tulisa Contostavlos at the bootcamp stage of the competition after they failed to get through as solo acts.

Previously known as, Rhythmix, the group were forced to change their name to Little Mix in October after it surfaced that a children's music charity had the same name.

The group are the first girl group to reach the finals and if they go on to win they will make history as the first group to ever win the X Factor.
