Keeping fit! Pregnant Mila Kunis stepped out with her growing baby bump in Los Angeles on Thursday, May 1 to take a yoga class.

The Jupiter Ascending actress paired her workout ensemble with black aviators and, of course, her engagement ring.

Us Weekly exclusively broke news last month that the That '70s Show costars are expecting a baby girl. "Ashton is doting on Mila," a friend told Us at the time. Another added: "Mila absolutely loves being pregnant."
