In her new book "Unbearable Lightness," the "Arrested Development" actress claims she started a diet -- and then couldn't stop, eventually eating just 300 calories a day. She detailed how she would eat a spoonful of tuna mixed with butter spray as a meal.

"It wasn't that I was proud of it, but it was certainly recognition of my self-control," Portia revealed.

Portia says meeting Ellen DeGeneres in 2004 saved her life. "I love her, and I'm very proud to be her wife."
