Mark Ronson has become the first act of 2015 to top both the UK's official singles chart and albums chart at the same time.
The producer, whose fourth studio album Uptown Special marks his first chart-topping LP in the UK, has described the achievement as "absolutely incredible".
He peaked at number two with his last two albums - 2007's Version and 2010's Record Collection.
The musician has also claimed a sixth non-consecutive week at number one with his single Uptown Funk featuring Bruno Mars with combined chart sales of 120,000.
The track was streamed 2.562 million times in the last seven days, the Official Charts Company said.
Mark told OfficialCharts.com: "This is absolutely incredible. I want to thank Jeff Bhasker, Michael Chabon and Emile Haynie who were there since the very beginning of this record - as well as Alison Donald, Mark Terry and Jason Iley at Sony UK.
"And finally, thank you to everyone who went out to the shop and bought the CD or pointed and clicked on Uptown Special this week - I really can't believe it."
Mark, whose album includes the worldwide smash Uptown Funk and two collaborations with Stevie Wonder, is the first act to achieve the official charts double since Miley Cyrus, who topped the singles chart with Wrecking Ball and the albums chart with Bangerz in the same week back in October 2013.
This week's second-highest new entry in the albums chart comes from Fall Out Boy, who after leading the chart at the midweek stage finish in second place with their sixth studio album American Beauty/American Psycho, trailing Uptown Special by less than 1,900 copies.
Ed Sheeran is at number three with X, Sam Smith is at number four with In The Lonely Hour, and George Ezra is at number five with Wanted On Voyage.

The track follows her global smash All About That Bass and is the second single from her debut album Title which is released tomorrow.
