Bruno Mars is celebrating a rare double in topping both the singles and album charts.
The US pop star's Doo-Wops & Hooligans album went straight to number one, selling 86,000 copies in its first week.
His track Grenade held off a challenge from Adele, one of five new entries in the top 10, to stay top of the singles chart. Mars is the first solo male act to achieve the chart double since Mika in 2007, with his debut album Life In Cartoon Motion and single Grace Kelly.
Grenade is the second number one single for Mars, who had been acclaimed for debut hit Just The Way You Are last year. The song is still in the top 20, falling one place to 18.
His recently announced tour has already sold out, including two nights at Koko in London which sold around 3,000 tickets in under an hour.
Rolling In The Deep, the opening single from singer-songwriter Adele's new album, entered the charts at number two.
Jessie J, winner of the BBC's Sound Of 2011, saw her first single Do It Like A Dude drop one place to number three.
Coming Home, the new release by US rapper Sean Combs' latest group Diddy-Dirty Money featuring Skylar Grey, went in at number four, while north London-based MC Wretch 32's debut single Traktor, featuring vocals from L, entered at number five.
Britney Spears scored her 21st top 10 hit in just 12 years with Hold It Against Me at number six, while Aggro Santos and Girls Aloud's Kimberly Walsh's Like U Like went in at eight.
Rihanna dropped to second slot in the albums chart with Loud falling behind Bruno Mars. New release Ritual from London rockers White Lies went straight in at three.
