Jay-Z got playful with his lyrics when performing in Ohio for President Obama's campaign, and changed up the lyrics to "99 Problems".

With the Presidential Election merely hours away, President Obama pulled out all the stops in the vital swing state of Ohio. During his campaign tour there he had rap icon, and known Obama supporter, Jay-Z perform and also rock legend Bruce Springsteen. While performing his classic track "99 Problems" Jigga changed up the lyrics to include Republican candidate, Mitt Romney.

As he was about to perform "99 Problems" Jay addressed the fans, "I have to do it, I'm sorry...I didn't get clearance from the Secret Service," and he announced the change of the hook, replacing "bitch" with "Mitt". Shawn Carter went on, "I changed the lyrics of this song. It goes like this: 'if you havin' world problems, I feel bad for you son/ I got 99 problem but Mitt ain't one."

Don't know if POTUS co-signed this improvisation, and it will be interesting to follow the backlash from Romney supporters. Check out the video below, courtesy of NYMag.
