The superstar couple will hold a fundraiser with Obama on Tuesday at a swanky New York nightclub that Jay-Z owns.
Tickets are $40,000, but the campaign says a small donation lands a chance to win two tickets -- airfare and hotel included.
Beyonce says in an email to Obama's supporters that she's a huge fan and will do whatever it takes to help him win a close race.
This isn't the first time the Obamas have teamed up with the A-list couple to promote each other's' causes. Michelle Obama helped Beyonce with efforts to promote global humanitarianism, and the president appeared in a pre-recorded video earlier this month at a Jay-Z event in Philadelphia.
