Which pop group admitted that they didn't actually sing on their hit 1990 album?

You know, if a producer ever wants to make someone a famous pop star without them ever actually having to sing, all I’m saying is that I’m available. 

We’re all familiar with the idea of singers lip syncing, usually when it’s for a halftime show or something like that. Especially when you’re a pop star who’s also dancing around on stage, I get it. Have you ever tried to sing while doing jumping jacks?

But there was one group who took things to the next level. Following rumors and news stories about them, not only did they admit to not singing on stage, they admitted to never singing on any of their recordings altogether — including on their 1990 album that was an international hit. Which group made this shocking admission?
