With her baby set to arriving in a few weeks, actress Mila Kunis is preparing for the birth of her first child by keeping fit and attending pre-natal yoga classes. On Saturday, Kunis was spotted at a Los Angeles yoga studio wearing yoga pants, a black top and white flip-flops. She left the studio after her session of pre-natal yoga to grab a bite with a friend, looking rosy and relaxed behind aviator shades.

The That ‘70s Show actress was seen sipping a healthy iced tea to accompany her lunch and talking animatedly with her friend. With the birth happening by the end of summer, it’s likely that the pair was talking about the baby girl Kunis will be having with fiancé Ashton Kutcher, as she has admitted to being excited about it.

Kunis told Marie Claire that she loves being pregnant and that she enjoys seeing her body change during the pregnancy’s course. She marveled about the change in her breasts, saying, “They’ve tripled in size. I was a 34A; now I’m a 36C. I’m so excited! I’m telling everyone I know, ‘Go ahead, touch them!'”

Kunis has also revealed that she is planning to have a natural birth for her baby daughter. She told talk show host Ellen DeGeneres in May that she and Kutcher had watched documentaries on midwifery as well as spoken to her obstetrician about it. They reportedly discovered that the hospital in which she was planning to give birth does have “a midwife, you know, doula type of thing.”

“So I’m gonna do it as all-natural as I possibly can unless there’s an emergency or something,” Kunis said.

Kutcher has been extremely supportive of his fiancée and plans to be present during the delivery, Kunis said. On Friday, he took Kunis on a romantic breakfast date at West Hollywood café La Conversation.
