Fifth Harmony top US iTunes chart

Fifth Harmony have shot to number one on US iTunes with their debut album Reflection.

Within minutes of it's release today, the girls hit the top spot, and have done so in over 20 countries already.

Featuring three Gold-certified singles including their latest chart hit, the Meghan Trainor-penned 'Sledgehammer', Reflection has won praise from Billboard and Rolling Stone among others.

The album also includes collaborations with Kid Ink ('Worth It') and Tyga on the Mariah Carey-sampling 'Like Mariah'.

Fifth Harmony, signed by Simon Cowell and LA Reid after wowing America on The X Factor USA, kick off their 22-date headline tour later this month.

The girls won the hearts of the UK when they made their first visit to perform 'Bo$$' on The X Factor semi-final in December. Stay tuned for further updates on Fifth Harmony's exciting UK plans.
