New York City's favorite gay, orange-hued weatherman Sam Champion, turns 47 today. Us Weekly editor Janice Min is also celebrating. It's her 39th birthday today, which makes her approximately 25 years older than the average Us reader. She isn't the only magazine star who will be munching on cake in the office today: Martha Nelson of People is 56. Other birthdays: Fidel Castro is 82, Danny Bonaduce is 49, and art maven (and heiress) Agnes Gund turns 70. And actor Sebastian Stan, who may be better known as Leighton Meester's boyfriend, turns 25.
