( CNN ) -- Mila Kunis -- and her baby bump and engagement ring -- are out of hiding . After shying away from discussing her pregnancy and relationship with Ashton Kutcher , Kunis has opened up to Ellen DeGeneres about both the baby and her future husband . In an episode of `` Ellen , '' the 30-year-old actress marveled that she and Kutcher , 36 , were able to keep their growing family and wedding plans under wraps `` for a very long time . '' `` 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 . '' Even when the cat was out of the bag , Kunis and Kutcher declined to make a public announcement , and they did the same with their baby news . On `` Ellen , '' Kunis was still coy about details -- she would n't reveal her due date , the baby 's gender or the name they 've chosen -- but she did jokingly confirm that the little one will arrive `` sometime this year , I promise you . '' So far , Kunis has had a `` stereotypical '' pregnancy , with cravings for salty snacks like sauerkraut and pickles . To help out his fiancee , Kutcher has stocked their `` secondary fridge '' with things Kunis might want , from ice cream to anchovies . `` He kind of pre-empted this . He assumed I was going to have goofy cravings , '' Kunis said . `` It happened last week . I was like , 'Oh my God , I need a pickle . ' And he was like , 'Hold on a second , ' and disappeared into the backyard and came back with the most amazing dill pickle of all time . '' That 's not the only way Kutcher 's trying to be helpful . He 's also learning Russian . Kunis , who 's from the Ukraine , already speaks the language , and he wants to be able to speak Russian to the baby , too . As far as her birth plan , `` I 'm going to do it as all natural as I possibly can , unless there 's an emergency , '' Kunis said , confirming that she plans to go without an epidural . `` I did this to myself , I might as well do it right .
