Laura Prepon thinks Mila Kunis and Ashton Kutcher will be "wonderful" parents.
The 'Orange is the New Black' actress Prepon is delighted her former 'That '70s Show' co-stars are expecting their first child together and thinks their baby is very lucky to have them as mother and father.
She told E! News: "They're going to be wonderful parents. I don't comment on my friends' private lives, but they're wonderful."
Mila, 30, recently admitted she loves being pregnant - because her breasts have grown.
She said: "They're amazing! 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!'
"Without being an a*shole, I have to say, I love being pregnant."
The brunette beauty - who got engaged to Ashton earlier this year - also admitted she has warned her fiance to stay "above the action" in the delivery room.
She said: "Two people are allowed in my delivery room: my doctor and my significant other. And [my future husband] is staying above the action. He'll be head to head. Not head to vag. Unless he wants to risk his life and see. But I wouldn't if I were him.
"I highly doubt he wants to see that being ripped apart and shredded. Because it will be shredded. It's just a matter of how badly."
