Earlier, the star posted a letter of thanks to Obama on her website, calling him a "leader to take us from where we are to where we need to be."

You are the reason my daughter and nephew will grow up knowing that they can truly be ANYTHING they want to be.

On Monday, Beyonce's husband Jay-Z performed many of his hits at a campaign rally in Columbus, Ohio for Obama. For "99 Problems," the hip-hop icon swapped out "bitch" with "Mitt" in one of the more spontaneous moments of election season.

"If you're having world problems, I feel bad for you son, I got 99 problems but Mitt ain't one," he rapped.

In September, the couple hosted a $40,000-per-ticket fundraiser for the Obama campaign at NYC's 40/40 club. The bash raised $4 million.
