Others marking birthdays on this downer-of-a-day: Moby is 43. Marie-Josée Kravis, the third wife of billionaire financier Henry Kravis, is 59. Rapper Ludacris turns 31. Brokerage founder Muriel Siebert is 76. Hedge funder David Tepper turns 51. Politico William Cunningham is turning 58. And crooner Harry Connick Jr. is 41.
