Consider this a warm-up for Beyoncé’s performances at the Super Bowl half-time show and BRIT Awards in February.

One of the President’s most prominent celebrity supports, Beyoncé and husband Jay-Z threw a $40,000 per ticket fundraiser for his campaign and wrote a moving handwritten letter on the eve of his re-election.
