Rihanna's sixth album, Talk That Talk, is back in the number one spot after 38 weeks in the charts.
The release, which features guest producers including rapper Jay Z and ex-boyfriend Chris Brown, topped the album chart on its release in November last year.
But the US-Barbadian pop star was back at the top, shunting teenage pop star Conor Maynard off the number one spot.
Maynard, dubbed the UK's Justin Bieber, fell to number six with his debut album Contrast.
He also dropped 10 places in the singles chart with Vegas Girl at number 19, the Official UK Charts Company said.
Plan B stayed at number two in the album chart with film soundtrack Ill Manors and Maroon 5 climbed a place to the third spot with their fourth album, Overexposure.
In the singles chart, East London grime star Wiley held on to the top spot for a second week.
His track Heatwave once again narrowly beat Calvin Harris whose track We'll Be Coming Back, featuring Example, remained at number two.
New entries Taking Over Me from UK band Lawson and Lost in Your Love from Bristol-based Dj Redlight stormed into the charts at three and five.
