Sure, it may not have been as memorable as Marilyn Monroe’s serenade to John F. Kennedy in 1962, but Oscar-winning actress Jennifer Hudson still helped President Barack Obama celebrate the big 5-0 in style Wednesday night at a star-studded party in Chicago.

Herbie Hancock and OK Go also performed at the party, where seats reportedly went for $38,500. According to reports, Obama will continue the festivities today, his official birthday, at the White House before a weekend trip to Camp David.

Check out J-Hud’s crowd-pleasing performance below.
