Former X Factor contestants Little Mix have managed to top the iTunes chart in the US with their latest album.

The group's second album “Salute” was released in the US today and has shot straight to the number one spot.

The girls managed to fend off competition from Bruno Mars with his album “Unorthodox Jukebox” which had climbed back up the charts following his performance during the Super Bowl half time show, and managed to receive a boost in their own sales following a performance on Good Morning America.

Little Mix are currently in the US to support Demi Lovato on her tour across the country but will be back in the UK to promote their cover of Cameo's “Word Up” which the girls have recorded in aid of Sport Relief.
