Mila Kunis, her engagement ring, and her baby bump made an appearance on The Ellen DeGeneres Show which aired on Friday (May 9). The 30-year-old pregnant actress opened up for the first time about her baby with fiance Ashton Kutcher and how the actor has stocked their fridge with "weird food" for her cravings. She also stated that she would be having a natural birth by using a midwife at home.

The "Black Swan" actress and Kutcher have kept mum about their engagement and their baby for a while. Kunis marveled that she and Kutcher, 36, were able to keep their growing family and wedding plans under wraps "for a very long time."

"Now you hid it for a while. I mean, you got away with it for a long time," replied Ellen Degeneres. "We were able to keep (our engagement) private for two months without anybody knowing," Kunis said. "I think everybody assumed we'd been engaged for so long, that I was wearing the ring in public for two months and nobody commented on it."

"He assumed that I was gonna have goofy cravings, so he stocked our secondary fridge with weird food," Kunis said. "Just like pickles, and sauerkraut, or like anchovies, and ice creams...just in case at one point during this pregnancy I'd be like I really want something. And it happened last week, I was like oh my God, I need a pickle. Like it was just the weirdest thing. Like I needed this pickle and he was like hold on a second and disappeared in the backyard and came back with the most amazing dill pickle of all time." She also talked about her cravings, saying, "I'm very stereotypical. I eat sauerkraut all day long."

The former "That 70s' Show" co-stars are planning on using a midwife for their baby's birth. "We watched a couple of documentaries and we looked into the like the you know midwife aspect of it and things and spoke to my OB/GYN and realized that the hospital that I'm going to be labouring in does have a midwife, you know, Doula type of thing."
