Calling all fans of cheesy, sing-along 1990s pop: girlband Eternal have been confirmed as part of the line-up for ITV2's The Big Reunion alongside Gareth Gates, A1 and Damage. The news that Louise Redknapp's chart-dominating, all female group were re-grouping even just for a single television programme got us compiling a list of next year's reported comebacks.

1) Outkast

The most high-profile reunion of 2014 will be that of hip-hop unit Outkast who are strongly rumoured to be returning with an appearance at California's Coachella festival. After a six year hiatus, Andre 3000 and Big Boi are reportedly finally back together and are not only planning a 2014 tour but possibly a new album too. A source told Billboard that it was "all systems go" for the hip-hoppin' duo who have set their sights on the US festival in April.

Though neither has been inactive since 2006's Idlewild, a return under the moniker Outkast would be a welcome shot of excitement for the hip-hop and pop worlds next year. Of course, if Outkast were to reunite, the legendary Coachella would be the perfect platform for them after numerous acts have re-entered the musical sphere, including Pixies in 2004, Rage Against The Machine in 2007, Pavement in 2010 and the scheduled exclusive headline acts the Stone Roses and Blur.
