The New Jersey native, 31, has no qualms about speaking her mind when it comes to men, diet or how she stays fit in Hollywood.
"I told my boyfriend after three weeks that I wanted to marry him and that we could do it tomorrow," Larter tells Cosmopolitan in its October issue.
And while such a pronouncement might scare off some men, the Heroes star and her boyfriend – actor Hayes MacArthur (who appears in the upcoming film The Game Plan) – have been steadily dating for two years.
"Now that I'm actually in love, I know that what came before wasn't real," she says. "It's about being there for each other through the ups and downs of life."
In terms of the future, she says, "I do want to get engaged and married ... and I look forward to that time when I'm home with babies."
Another issue where Larter is equally brazen: Her approach to diet, especially given Hollywood's rigid standards for female stars. "I love wine, bread and cheese," she says in the interview. "I just have to cut out the bread sometimes."
Larter, who characterizes her approach to food as being "just like every other girl," explains that it's all about moderation and balance. "Last night, I drank some merlot and made potatoes au gratin with a rib-eye steak," she says. "It was amazing. I hope to always find that balance."
For Larter, her approach to life – and her attitude – stem from growing up on the East Coast and nurturing a career largely outside of the Hollywood system.
"I'll always be a Jersey girl," she says. "I don't always get my way, but you'll know exactly how I feel about it."
