Miley Cyrus has become the first artist this year to top both the single and albums charts at the same time.
The American pop singer beat Eminem to the top single with her song Wrecking Ball.
Her album Bangerz beat Chase & Status' Brand New Machine into second place.
The last act to achieve the chart double was Olly Murs, with his single Troublemaker and album Right Place, Right Time, last December.
"I truly appreciate the love I'm getting from the UK", the singer said. "Not only is this my second number one single, but even more amazing is the fact my album has also gone in at number one. I can't wait to be back in the UK next month."
