"If you’re having girl problems, I feel bad for you, Son. I got 99 problems but Mitt ain't one," he rapped at the rally, said the Washington Post.
Jay-Z changed the words to one of his most popular songs. "Mitt" of course refers to Republican presidential nominee Mitt Romney. Jay-Z was on hand to warm up the crowd before the president took the stage.
"I didn't clear this with Secret Service so hopefully they won't tackle me," Jay-Z told the crowd.
The Secret Service must have been OK with the song, because the rapper was not tackled at the rally. He did follow up the song with an "odd choice," according to the Washington Post. He followed up "99 Problems" with "on to the Next One."
"Jay-Z and wife Beyonce have been high-profile supporters of Obama's, hosting a celebrity-filled fundraiser in Manhattan a few months ago," said the newspaper. "Beyonce recently wrote a letter of thanks to first lady Michelle Obama for being a good role model and has appeared in campaign videos."
Jay-Z has been busy with more than supporting his favorite candidate. He recently helped bring the New Jersey Nets to Brooklyn, New York, helping to open the arena in his hometown to make that possible.
In an interview a few months ago, he did mention the one thing he hasn't been busy with. E! News asked if he and wife Beyonce would be having another baby anytime soon.
"Not in one, two, three, four, five, six, seven, eight or nine months," he answered.
He does feel like he is living the American dream though, and the basketball team is part of that.
"He never dreamed he'd own a basketball team," said John Carucci with the Associated Press. "Now Jay is part owner of the Brooklyn Nets and instrumental in moving the franchise from New Jersey."
Jay-Z didn't mention whether he thinks President Obama was partially responsible for that American dream, but it looks like he is happy enough with the way things are going to be voting for the president on Tuesday.
