Mediabistro founder Laurel Touby is turning 46. Common is 37. Danny Masterson is 33. Dana Delany is 53. And Neil Sedaka is turning 70. Weekend birthdays after the jump!

Glenn Close walking her dogs in Central Park ... James Gandolfini making faces at photographers outside the Milk after-party at the Bowery Hotel ... Madonna walking on the sidewalk last night ... Natalie Portman carrying her dog and a cup of coffee ... Brooke Shields, Kim Raver, and Lindsay Price filming scenes for Lipstick Jungle on the Upper East Side ... Twilight star Robert Pattinson arriving at JFK ... Katie Holmes leaving her apartment on East 13th and later shopping at Dean & DeLuca with Suri ... and Beyonce unveiling her Seventeen cover at the Hearst building.

For a while it looked as if weekly topless scenes of Robert Buckley would keep Lipstick Jungle in business, but it seems that one man's perfect abs can only do so much: NBC has axed the Candace Bushnell adaptation after a move to the Friday lineup failed to make more viewers believe that massively powerful businesswomen juggling relationships, children, and perfect designer wardrobes would also have time to meet every day for breakfast, lunch, cocktails, and dinner. Of course our sympathies go out to the cast of Brooke Shields, Lindsay Price, and Kim Raver (as well as to the cast of My Own Worst Enemy, which NBC also canceled). But you know who we feel most sorry for? Bushnell's ballet dancer husband. This news is not going to improve her already volatile mood.
