Break out the Cristal. Mr. Sean Combs turns 40 today. Perhaps he'll get together later to celebrate with Bethenny Frankel of the Real Housewives of New York: She's turning 39. Others blowing out candles today: Matthew McConaughey is turning 40. Kathy Griffin is turning 49. Laura Bush is 63. Survivor host Jeff Probst turns 47. Author Charles Frazier is turning 59. Playwright Jon Robin Baitz is 48. Literary agent Andrew Wylie is turning 62. Publishing industry honcho Jonathan Galassi is 60. Anne Sweeney, the president of Disney/ABC president, is turning 51. Ralph Macchio of Karate Kid fame is 48. And Trishelle from The Real World is 30.

Not only does Diddy get to vote or die today, he gets to celebrate his birthday, too. He's 39. There probably won't be much to celebrate in the White House today, but Laura Bush will have one reason to. She's turning 62. Also celebrating: Literary agent Andrew Wylie is 61. Playwright Jon Robin Baitz is turning 47. Book publisher Jonathan Galassi is 59. Matthew McConaughey is celebrating his 39th. Kathy Griffin is 48. Disney/ABC president Anne Sweeney is celebrating the big 5-0. Walter Cronkite is 92. Survivor host Jeff Probst is turning 46. Author Charles Frazier is 58. And the Karate Kid, Ralph Macchio, is 47.

Though it happened on the pages of the apparently profitable Huffington Post, it could have just as easily have been on an episode of the Hills. Dreamboat playwright, blogger, and writer for ABC's Brother and Sisters Jon Robin Baitz responded at length to an incredibly patronizing and, well, shitty piece Times Theater critic Charles Isherwood wrote. Isherwood had wondered "whatever it is television and movie writers do when they are not cooking up dialogue for detectives, superheroes or nerdy, horny teenagers." "You, sir, are a dick," Baltz replied. (Okay, paraphrasing!)
