So does President Barack Obama and Jay-Z have beef? Recently President Obama was worried the rapper's controversial trip to Cuba would cost him the White House ... this according to Jay-Z. 

Hova just released a new rap, in which he addresses all of the drama surrounding his trip to Cuba last week with his wife Beyonce.

 In a new interview, Ray-J implied that his new song "I Hit It First", ISN'T about Kim Kardashian and Kanye West . . . even though it totally is.  He said, "It's a song, it's not about that, it's about a concept.  People going way too deep . . . I'm not trying to create no war, it's all love.  We're doing music." You be the judge.
