Newly reformed boyband Blue have rocketed up the iTunes chart thanks to their recent addition to ITV's 'The Big Reunion'.

The quartet were a surprise addition to the show's line up, which also includes B*Witched, Atomic Kitten and 5ive, and their 'Best of Blue' compilation record has climbed to No.7 on the UK iTunes albums chart.

'Best of Blue' features such hits as 'All Rise' and 'U Make Me Wanna' and the band are set to release a brand new offering, entitled 'Roulette', next month on April 29.

Meanwhile, Blue have also unveiled the new UK video for 'Hurt Lovers', which will act as the lead single from 'Roulette'. Fans can pre-order 'Hurt Lovers' on iTunes now and it will be released as a single on April 22.

Tweeting about their new-found iTunes chart success this afternoon (March 15), the group thanked their fans and described it as "humbling": "It's been an incredible day here in the UK. Thanks for all the support & love, It's humbling to see our greatest hits in the iTunes Top 10.."
