Ed Sheeran has revealed he's already got his next four album titles lined up.
Next year will see the singer - who's good friends with Taylor Swift - release the much-anticipated second album of his career after the huge success of his debut album '+'.
Quizzed whether his second album's title will follow the mathematical theme of his first, Ed exclusively told BANG Showbiz: "It'll be mathematical. Maybe Pi [π]? Then you can have a slice of the pie ... No! It'll be a title along the lines of ['+'].
"I've had the four titles for the next four albums in my mind for a while, so they'll come out [eventually]."
The 22-year-old star - who has spent the last year touring America with Taylor Swift - is hard at work on his next record and says his comeback track will be hitting radio sooner rather than later.
He teased: "The album will be out next year and I think the first single comes out early next year. Really, really early."
Ed performed for the first time on British soil on Sunday night (29.09.13) in nearly a year at benefit show A Concert For Stephen Lawrence held to remember a young Londoner who was slain in a racist attack in 1993.
Ed hopes the charitable gig will have a positive effect on the fans in attendance and help draw attention to the effects of racism.
He said: "Probably 90 per cent of the audience coming wouldn't have been alive at the time when it was all very prominent. So it just brings it back into the public spotlight. It means a lot to be asked to be part of such an amazing line-up for such a great cause."
Other stars who thrilled fans at The O2 arena in London included Rita Ora, Jessie J, Ellie Goulding, Rudimental, Tinie Tempah, Labrinth and Beverley Knight.
Jessie performed an incredible rendition of hymn 'Amazing Grace', while Rizzle Kicks covered The Beatles classic 'Blackbird' - which Sir Paul McCartney was inspired to write about the black civil rights movement in the US in 1968.
Emeli Sande closed the concert with three tracks including 'Next To Me'.
