Mila Kunis
is revealing her secret to a perfect date night -- being comfortable!

The "Jupiter Ascending" star is dishing about spending quality time with boyfriend Ashton Kutcher in the February issue of Cosmopolitan magazine.

"I'll tell you: we have a thing called white T-shirt night and it's when you wear jeans and a white T-shirt and you go on a date," the actress told the mag. "Nothing fancy, it's just something that you love to do." 

"And whether that's bowling or dinner or going to a cheese shop and have some wine or walking around," she added. "I think that's just the best thing to do — and sometimes it's just nice to stay home."

The former "That '70s Show" costars have been dating for nearly two years and are still going strong.

In addition to her date night details, the brunette beauty also admitted that sexy isn't a word she uses to describe herself.

"Oh no, no. I really don't. I don't see myself as not-sexy, it's just not [one of] the top 40 adjectives I would use to describe myself," the-30-year-old explained. "But I do see myself as confident, but if someone sees me as sexy I'm not going to argue that and say 'no I'm not, you're crazy.' I'll just say 'thank you' politely."

We love how humble she is!
