Jay-Z and Kanye West were both out and about in NYC today. The rap superstars have been putting the finishing touches on their new collaboration, Watch the Throne, which Kanye says is slated to come out any day now. Jay and Kanye are back on the East Coast after ringing in 2011 with Beyoncé Knowles and friends like Gwyneth Paltrow and Chris Martin in Vegas. Kanye has been relatively quiet on Twitter since New Year's, though he did take the time to RT the viral video of Josh Groban singing the rapper's 140-character missives. Fans are anxiously awaiting Jay-Z and Kanye's album, and perhaps the two will take the stage together at next month's Grammy Awards, where they are both nominees.
