Casual stroll for three! Pregnant Mila Kunis stepped out with fiancé Ashton Kutcher and their dogs on May 1 in Los Angeles.

In a loose-fitting tribal print tank dress, Kunis, 30, covered her growing baby bump as she trailed behind Kutcher, 36, who dressed down in sweats, a plain T-shirt, and Chicago Bears cap.

The mom-to-be has been keeping active throughout her pregnancy, taking everything from Pilates classes to pre-natal yoga classes.

Donning a black tank which read, "I've Got Sunshine," the expectant Black Swan actress stepped out earlier that same day to take a yoga class.

All the physical activity is serving her well -- Kunis "feels good" and "is having a good pregnancy," a source recently told Us. What's more, the source added, soon-to-be-dad Kutcher "is so happy and will do anything for her." In fact, an insider adds, the Two and a Half Men actor has even been "eating healthier."

This will be the first child for the couple, who are expecting a baby girl. The former That '70s Show costars first went public with their relationship in spring 2011 and got engaged this past February.
