Hip-hop’s royal couple will host the nation’s first couple at a Sept. 18 fundraiser to boost President Obama’s re-election bid.

Jay-Z and wife Beyoncé will host the commander-in-chief and First Lady Michelle Obama at the “Watch the Throne” rapper’s 40/40 Club in New York City, the New York Post has reported.

The event is an intimate affair, where about 100 guests will pony up $40,000 to dine with the two power couples.

The planned dinner is the latest sign of the friendship that exists between the Obamas and the hip-hop superstars. Early in his first run at the White House, then-Sen. Obama hailed Jay-Z as one of his favorite rappers. The hip-hop mogul and his wife both performed at a tribute concert the night before the president’s inauguration.

Since then, Beyoncé has contributed to the first lady’s “Let’s Move!” health initiative. She has also had a hand in their election campaign. The Obama campaign tapped her to read a previously posted letter of appreciation to Michelle Obama in a web video and she attended a March fundraiser hosted by the first lady with her mother, Tina Knowles and mother-in-law.
