Boyband One Direction unveiled their DVD for 'This Is Us' earlier this week and the release has already broken an exciting sales record. 

According to the Official Charts Company, the heartthrobs shifted an incredible 170,000 DVD/Blu-ray copies during the first day, which has given them the biggest first-day sales figures for a music DVD/Blu-ray in UK chart history. 

Official Charts Company chief executive Martin Talbot issued a statement on the lads' exciting new achievement, which reads: "It has been quite a year for 1D and their fans - and they are continuing that right through into Christmas."

"Every act goes into the festive season hoping to secure the Official Christmas Number 1 album, but if they manage to pull off the album and video double at such a competitive time of the year - that will be some achievement. If current performance is maintained, we could be looking at a 1D Christmas in 2013!"

The 'Story Of My Life' superstars opened up about their plans for the Christmas period and Niall Horan explained that eating will be a big part of his own holiday: "I think we're all just going to go home be with our families for a little bit, eat lots of food and get really fat."
