Some lucky party goers at Gabrielle Union's 40th birthday party in Miami Saturday night witnessed a rare performance from the Fresh Prince himself, Will Smith. The A-list action star grabbed the mic while Doug E. Fresh provided the human beatbox, and spit some lines -- including an out-of-character n-bomb -- before doing a brief medley of "Summertime" and the Fresh Prince of Bel Air theme.

The captives at Guantanamo Bay may be stuck there indefinitely, but the librarian has their back.

From today's Miami Herald:

Harry Potter books are passé among the prisoners. The adventures of the boy wizard have been supplanted by early episodes of Will Smith's 1990s TV comedy, The Fresh Prince of Bel-Air, as a popular way to pass time among the 168 captives now in their second decade of U.S. detention.

"I just ordered all six seasons," says librarian Milton, a Defense Department contractor who gives only his first name to visiting journalists."

Most prisoners can watch the show communally "pretty much around the clock. ... A maximum security captive, who represents about 15 percent of the population, can watch the show alone for perhaps an hour or two a day."

It's been an entire decade since Will Smith has recorded a title rap for one of his movies, and it seemed like Men in Black III would be the perfect opportunity for the Fresh Prince/galaxy defender to step to the mic one more time.

So, the producers of the movie did the logical thing ... they hired Pitbull?!

The folks at Sneaky Zebra are understandably not nodding their heads about this state of affairs.

The Fresh Prince himself recently visited the BBC's The Graham Norton Show, where he rapped his legendary intro -- but now without a major assist from the all-British audience.

Family Reunion of the Day: Will Smith recently reunited with his Fresh Prince of Bel Air castmates James Avery (Uncle Phil), Karyn Parsons (Hilary), Tatyana Ali (Ashley), and Alfonso Ribeiro (Carlton).

"There's nothin' like spending Holidays with fam!" Smith wrote on his official Facebook page.

The roles of Janet Hubert-Whitten (Vivian 1) and Daphne Maxwell Reid (Vivian 2) were played by two random white dudes.
