After spending 10 hours doing a full day of press at San Diego Comic-Con for her new show "Legendary," actress Ali Larter just wanted to unwind — with a mammoth bacon cheeseburger.

Larter posted a picture of herself and the massive burger to Instagram from the car on her ride home from the convention, and swung by the Orange Room to dish on the photo.

"I'm a girl who actually eats bacon cheeseburgers," Larter said. "I got in the car on the way home and had my bacon cheeseburger, my french fries, my extra mayo, pickles, and I ate the whole thing."

Larter may have enjoyed every bite of the burger while she was eating it, but said that sure enough, a fan had to be a buzzkill and reveal its calorie count. 

"A fan tweeted me and said 'I can't believe you at that 1400-calorie burger!' ... I definitely went for a jog the next day," Larter joked.
