Celebrating her 39th birthday, QUEEN LATIFAH and dozens of pals donned their booze goggles and danced their booties off at S.I.R. recording studio on Sunset Blvd., where you can rent rooms for private bashes – but precisely at 2 a.m., the responsible Queen made all her friends take Breathalyzer tests, then sent those who failed home in taxicabs!

Hail to you, Clever Queen.
