"I really wanted to go to college, and it all kind of happened at the same time," she says about posing for Gear magazine, which freed her from her "7th Heaven" contract after the show's fourth season. "I did this photo shoot. The photo shoot came out. It was terribly embarrassing. I had to apologize to everybody, including my parents. It was a big learning experience -- learning how to have boundaries and how to say no."
