*Cher has reportedly recorded vocals for the new Wu-Tang Clan album – and we do mean album, as in one copy of it.

As previously reported, “Once Upon a Time in Shaolin” is the  album that the legendary hip-hop collective has recorded in secret over the past year, and they are only releasing one copy of it. The 128-minute opus will be heard at galleries, festivals and exhibitions yet to be announced, and then sold to the highest bidder.

According to Forbes, Cher appears on two songs. At the end of one track, she sings the line “Wu-Tang, baby. They rock the world.” A rep for Cher has confirmed the collaboration, saying, “She recorded her parts separately, so I don’t believe there was direct interaction.”

Cher aficionados who happen to be Wu fans should have seen this coming for weeks: on the official web site for the album, it reads that “Bonnie Jo Mason” will make a guest appearance on the album. Bonnie Jo Mason is the name Cher used to release her first single, “Ringo, I Love You,” in the early 1960’s.

“We’re about to sell an album like nobody else sold it before,” Wu-Tang mastermind RZA said in March, when the project was announced. “We’re about to put out a piece of art like nobody else has done in the history of [modern] music. We’re making a single-sale collector’s item. This is like somebody having the scepter of an Egyptian king.”
