Gabrielle Union is going on a world tour (‘world’ being a bit of an exaggeration, here), celebrating her 40th birthday.

Last week, we shared photos of her NYC rooftop party and over the weekend, she celebrated in Miami with a private birthday bash (later, she partied at a Miami night club, where Will Smith hopped on the mic for an impromptu set), pajamas required! Gabby and friends wore their pj’s and sang happy birthday. We spotted Gabby’s boo, D.Wade, Jason Bolden, Lindsay Faulk, Savannah Brinson (Lebron James’ fiance), Chantel Christopher (Rocsi Diaz’s manager) and Ricky Williams. Peep some of the pix.

P.S. Am I the only one that loves the fact that Gabby’s rocking a headscarf?
