It's the middle of summer, but Mila Kunis looked incredibly cool on Saturday, July 26, in a printed wrap skirt and fitted maternity tank top. 

The pregnant actress, 30, wore the casual look while out to lunch with fiance Ashton Kutcher and another couple at Musso and Frank Grill in Hollywood. She flashed a playful smile at photographers while walking through the parking lot in her neon flip-flops. 

In the August issue of W magazine, the notoriously private Kunis opened up about her views on marriage and her relationship with her former That '70s Show costar Kutcher, 36. 

"I never wanted to get married. From the age of 12, I prepared my parents for no marriage," the mom-to-be told the publication. "Then things changed—I found the love of my life. Now my theory on weddings is: Don't invite anyone. Do it privately and secretly. My parents are okay with that. They're just excited that I said yes."
