As with the Opening Ceremony two weeks ago, details of Sunday's Closing Ceremony of the London Olympics have been kept tightly under wraps, but one thing is certain — British talent will be front and center.
In addition to the Spice Girls, who reunited especially for the event, the celebration, titled "A Symphony of British Music," will also feature performances from One Direction and the also-reunited Wham!.

Acts that are rumored, but not confirmed, to be participating include Coldplay, Muse, The Who, Queen and Annie Lennox, according to London's Daily Telegraph.
With more than 4,000 performers scheduled to take part, the Closing Ceremony will also likely feature appearances by British celebrities such as Russell Brand, Kate Moss and Naomi Campbell, the Telegraph reports.
Bob Costas, Al Michaels and Ryan Seacrest will be hosting the event for NBC, as London hands over the Olympic flag to Rio, the host of the 2016 games. Rio is also scheduled to make a "samba- and Carnival-flavored cultural presentation" during the ceremony, according to a press release from the network.
NBC's coverage of the Closing Ceremony festivities begins Sunday at 7 p.m. ET. A sneak preview of the new comedy series Animal Practice will follow.
