Justin Timberlake will make a surprise appearance at London's Live Earth concert at Wembley Stadium this Saturday.

Reports in the Sun newspaper this morning suggested the popstar would perform and this has since been apparently confirmed by the NME after it published the full lineup for the concert on its website.

The final batch of tickets for the event went on sale yesterday evening, priced at £55 each.

About 5,000 more tickets were made available and are being sold on a first-come-first-served basis.

Acts performing at the event include Madonna, Kasabian, Paulo Nutini, Black Eyed Peas and Snow Patrol.

A host of guest stars will also chat to the crowd and introduce some of the acts, with comedian Ricky Gervais appearing for the second consecutive weekend at the new Wembley.

According to the NME report, Chris Moyles will be getting the show underway by introducing Genesis.

They will give way to Razorlight before sets from Snow Patrol, Kasabian, Black Eye Peas and John Legend.

Former US vice president Al Gore will also speak at the concert from Washington and comedian Chris Rock will introduce the Red Hot Chili Peppers.
