USA (REUTERS) - British singer Adele once again kept her reign at the top of the weekly US Billboard 200 album chart on Monday (Feb 29), holding off albums by Rihanna and Justin Bieber.

Adele's 25, the top-selling album of 2015, notched another 100,000 units last week in album and song sales and streaming activity.

Her album has sold more than 8.3 million copies in the US since its November release and has spent ten non-consecutive weeks at the top of the Billboard 200 chart.

The singer also swept the BRIT Awards last week, the top music honors in Britain, with four wins including album of the year.

R&B singer Rihanna's latest album climbed one spot to No. 2 with 80,000 units sold, while Canadian pop star Bieber's "Purpose" dropped one spot to No. 3 with 63,000 units sold.
