Last month, the 5-foot-4 blonde beauty explained to Us Weekly that she's not naturally blessed with a slim and trim figure.
"I work my ass off! It's not easy," she said in September, adding that she exercises almost every day. "Seriously, when I'm not working, I'm working out. I'm not the kind of girl who stays skinny. Plus, I like to eat sweets! I like to eat a lot."
To keep things interesting, Seyfried sweats it out in several different ways. "In New York, you can do anything. I go boxing regularly with my friend Andrew. I do Barry's Boot Camp religiously when I'm in New York and I'm going to start going in LA now too," she said. "Plus, I have my trainer Harley [Pasternak] in LA."
