Mila Kunis flashed a big smile when she went on a casual lunch date with Ashton Kutcher and another couple in Hollywood on Saturday. The actress's growing baby bump was on display as she walked around the parking lot of Musso and Frank Grill while wearing a fitted white tank top and flowing maxi skirt. Mila and Ashton have been spending quite a bit of time together as they prepare for the arrival of their first child. The couple went on two burger dates in a row earlier this month, sparking suspicions that Mila might be craving burgers during her pregnancy. Despite their frequent outings together, Ashton and Mila were briefly split up in mid-July when Ashton flew to Brazil to watch the World Cup final.
