Jay Z and Justin Timberlake continue their lovefest from their Legends of the Summer tour, this time confronting their struggles with success in the new video for "Holy Grail," the opening track from Jay's Magna Carta...Holy Grail.

As Billboard reports, "Holy Grail" is the first video to have its premiere on Facebook, as the rapper negotiated a 24-hour exclusivity window with the company before it hits YouTube and other video sites.

"What we’re doing with Jay Z today is really exciting and we think emblematic of the evolution for music and how musicians can connect with their fans," Nick Grudin, head of content partnerships for Facebook, told the magazine. "And we think that is particularly evident in Jay Z’s approach here, which will really allow him to go direct to a massive and instant global audience. It's something that only Facebook I think can really deliver in this way, given the scale of the audiences musicians have and the global nature of those audiences and the social dynamics of what happens when they engage on Facebook."

The rapper released the Anthony Mandler-directed video on his Facebook page, juxtaposing scenes of him watching Mike Tyson lose the heavyweight championship with Timberlake singing in front of an exploded car that would make Michael Bay proud.

Mandler is no stranger to Jay, having directed 2006's "Lost One" and 2009's "D.O.A.," "Run This Town" and "Young Forever."
