Boyzone have reached number one in the UK with their album Brother.
Gorillaz had been on course to top the charts with Plastic Beach but Boyzone ended up selling more copies of their record, their first album since band member Stephen Gately passed away in October.
"We're just over the moon," band member Ronan Keating told Radio 1. "We can't believe it. It's quite emotional for us to be honest. We've worked hard on this one for obvious reasons.
"It's been an emotional time for us and for the album to go to number one was very important for us on so many levels."
There were two other new entries in this week's top ten; Amy MacDonald reached number four with A Curious Thing while the original cast recording of Love Never Dies entered at number ten.
However, Ellie Goulding's Lights, which was number one last week, dropped down to number 16. Rihanna's Rated R fell six places to 15, while Jason Derulo's self-titled album slipped from number eight to number 29.
