Amanda Seyfriend claims she's not the "kind of girl who stays skinny," so she soaks up a lot of her spare time at the gym. "I work my ass off! It's not easy," the 25-year-old said (via Us magazine). "Seriously, when I'm not working, I'm working out." She also exercises to curb the damage done by her sweet tooth. "Plus, I like to eat sweets! I like to eat a lot," she added. "I had a hamburger for lunch. It's like, 'What the f**k? Who cares!' I like to eat."
