"Wu-Tang, baby! They rock the world!" Mmm, yeah, that sounds about right coming from a 67-year-old.

In an interview with Forbes, producer Cilvaringz revealed that Cher will appear on the upcoming one-of-a-kind album from the Wu-Tang Clan, Once Upon a Time in Shaolin. Supposedly, only one copy of the album will be pressed. It will tour galleries and eventually be sold to the highest bidder. Wu-Tang producer RZA says he's been offered $5 million for the album, probably from someone who also thinks that the Wu-Tang Clan rocks the world and doesn't realize that the group as a proper unit hasn't been relevant for almost 15 years.

Rolling Stone has confirmed that Cher has lent her vocals to yet another, as-yet-unheard Once Upon a Time in Shaolin track.

Cher's rep told Rolling Stone that the diva recorded her parts separately and "so I don't believe there was direct interaction." Well damn. But still: Cher! Cher! I can't wait till Lord Jamar gets his paws on this one.
