When a pop group breaks up, it's often a race to see which former member can make it to the top of the charts first. These artists did that and so much more.
The icing on this 'don't-call-it-a-comeback' cake is that the show will feature one of the original pop stars from the ultimate boy band era: Nick Carter (arguably the cutest of the Backstreet Boys). And joining Carter is Emma Bunton, a.k.a Baby Spice (but why tho?) via revolutionary '90s/'00s girl band quintet Spice Girls.
