Bernie Kerik, the disgraced former NYC police commissioner, turns 52 today, although we imagine that this year there will be no celebratory hugs from his former boss. Today is also Beyonce's birthday: the singer, actress, and wife of Jay-Z is 27. Celebrity DJ Mark Ronson turns 33 today. One of the many contenders for mayor in 2009, Anthony Weiner, is 44. Mike Piazza is 40. Damon Wayans is 48. And Shar Jackson, the woman gave birth to Kevin Federline's kids before he found Britney to do the job, is 32.
