March 26 marked the 75th birthday of the inimitable Diana Ross, who celebrated among good great company at the Warwick in Los Angeles.

Beyoncé will receive a very special honor herself at this week's 30th Annual GLAAD Media Awards. Alongside husband JAY-Z, B will be presented with the Vanguard Award for their work as "global icons and passionate defenders of human rights." It's not publicly known just yet whether the two will attend the ceremony, which is being held at the Beverly Hilton hotel this Thursday.
