Sia has bagged her first US No.1 album.

The singer and songwriter recently released her latest effort '1000 Forms of Fear' and it has debuted at the top of the Billboard 200.

It shifted 52,000 copies in its first week to beat off competition from the Frozen soundtrack.

However, its figures is the lowest for a No. 1 album in nearly two years, with Zac Brown Band's 'Uncaged' selling 48,000 units in 2012 to reach the top of the chart.

'1000 Forms of Fear' features the likes of the single 'Chandelier'.

Sia's last album 'We Are Born' reached No.37 in the US in 2010, whilst her 2008 effort 'Some People Have Real Problems' reached No.26.
