The more fans think they know about Jay-Z's upcoming album, Magna Carta Holy Grail, the less they realize they truly know about the rapper's 12th solo album: last week it was believed the entire track list and guest appearances were revealed, but today fans learned that fellow rap veteran Nas will appear on the album as well.

The Queens rapper will be featured on the song BBC, which also stars Justin Timberlake, Beyoncé, Swizz Beatz, Pharrell and Timbaland. Timberlake and Mrs. Carter were already named to the album's guest appearances, when what was believed to be the final track list and featured artists was released on Thursday. However, yesterday fans discovered that Nas will also appear on the album with several of the album's producers. Swizz Beatz, Pharrell and Timbaland were expected to provide the instrumentals for the record, after they appeared in the Samsung commercial that took a behind-the-scenes look at the making of the record. What wasn't known until now is that the producers would lend their vocals to the album.

All three producers have rapped/sung to varying levels of success on their solo albums as well as in the capacity in which they'll be featured on Magna Carta Holy Grail. And though some of the verses and the chorus from BBC were released, it's not clear which producer handles the hook, which samples lyrics from the Mase hit Feel So Good.

"What you know about going out/Head west/Maybach 3 TVs all up in the headrest," the chorus reads.

Nas wasn't too forthcoming when asked about his involvement in Magana Carta Holy Grail by Vibe magazine on Thursday.

"It's Rat Pack-ing," Nasir said. "We were definitely recording. Magna Carta was going down. Some Justin Timberlake new album stuff was in the next room. Timbaland. D'USSE. Hennessey. Good times."

It seems Jay-Z made everyone who worked on the album agree to secrecy.
