The London Games will come to a close with a three-hour musical extravaganza which will feature performances by some of the UK’s top acts past and present.
The closing ceremony is scheduled to start at 21:00 BST and will air live in the UK on BBC One/BBC One HD.
Some of the names rumoured to be performing include Blur, Take That and the Spice Girls, while speculation is mounting that reclusive 1970s star Kate Bush will make a shock appearance.
George Michael, The Who's Roger Daltrey and Pete Townshend, Ed Sheeran and English rockers Muse are all scheduled to appear.
Rehearsals for the ceremony, which will feature over 4,000 performers, have been taking place in secret locations in London throughout the week.
Although organisers Locog have been keen to keep the list of performers secret, former Wham singer George Michael announced his involvement via Twitter.
"Spending most of the week rehearsing like crazy for the Olympic closing ceremony," he wrote.
"Obviously a bit nervous not having played for nearly a year, but rehearsals sounding good."
The show is also expected to feature a tribute to British fashion, with supermodels Kate Moss and Naomi Campbell rumoured to be involved.
The broadcast, which is expected to be watched by up to one billion people worldwide, will come to an end at around midnight local time with a huge firework finale.
