X Factor stars One Direction have landed a midweek No.1 today (September 14) with their debut single, 'What Makes You Beautiful'. 

Not only are the lads on course to top the charts this week, they are also on their way to score the fastest-selling single of 2011. This impressive title will be theirs if the track continues to sell as quickly as it has been since its release and the Official Charts Company explained:

"A glimpse at the latest sales figures for the week to date sees eagerly anticipated debut single, What Makes You Beautiful, blasting ahead in the race for the Official Singles Chart Number One this weekend."

Pixie Lott's 'All About Tonight' has dropped 2 places to No.3 and Maroon 5's latest offering, 'Moves Like Jagger', is currently at No.2. 

There's only one other new entry in the Top 20 this week and it comes from Noel Gallagher's High Flying Birds with their track 'AKA... What A Life!'.

The positions will be confirmed on Sunday, September 18 and you can watch One Direction's video for 'What Makes You Beautiful' below:
