Fifty-eight years ago today, a baby named Arianna Stassinopoulos was born in Athens, Greece; these days you know the liberal-turned-conservative-turned-liberal as Arianna Huffington, the founder of The Huffington Post. Also celebrating on this 15th day of July: Paul Sevigny is 37. Actor Forest Whitaker is 47. The future Mrs. Howard Stern, "model" Beth Ostrosky turns 36. Don Hill is turning 64. Real estate scion Dan Tishman is 53. Interior designer David Easton is turning 72. And adman Mitch Oscar is 56. Most importantly, it's Brian Austin Green's birthday today, too. Be a little extra generous with your loose change if he's your barista today.
