Put away your assumptions about Macaulay Culkin. The former child star's girlfriend says he's a homebody.

Culkin, star of the 1990 comedy "Home Alone," has been dating actress Mila Kunis for nearly six years; Kunis, who co-starred on TV's "That 70's Show," says they make a low-key couple.

"We enjoy each other's company," the 24-year-old actress says in an interview on Parade.com. "We like to read books or play video games or watch TV or go to the movies. And he's an amazing cook. He makes dinner every night."

Culkin made headlines several years ago when he was arrested in Oklahoma City on misdemeanor charges of possessing medication without a prescription and marijuana. He later pleaded guilty and was given a deferred sentence.

Kunis says Culkin, now 27, is more mature than people might think.

"He's an amazing, simple guy, who is probably the most brilliant person I've ever met," Kunis gushes. "He's so, so smart and so aware and so kind and so sweet. Unfortunately, that's not what people want him to be, so they write stuff."

Kunis says journalists misconstrue facts -- or "just make stuff up" -- about their relationship.

"At one point, they were like, `Seen shopping in Beverly Hills for engagement rings,"' she says. "We were in Japan working. What is wrong with these people?"

Kunis, who recently appeared in the film "Moving McAllister," will next be seen in the upcoming comedy "Forgetting Sarah Marshall." She portrayed princessy Jackie Burkhart for eight years on "That 70's Show," where her brunette beauty was prominently on display.

But Kunis is no girly girl.

"Listen, I am such a nerd," she says. "I'm not one of those girls that goes, `Ha, ha, hee, hee. I'm a nerd.' No, no, no -- my brain mentality is the same as a 12-year-old little boy. The video games that I play, the things that I like to watch -- I'm a Trekkie."
