Ashton Kutcher's twin brother opened up to Us Weekly about his expectant famous brother and Mila Kunis. Us caught up with Michael Kutcher on Monday, June 23, at the Harboring Hearts 2nd Annual Summer Soiree in New York City.

"My sister and Ashton are both expecting-it's so exciting for the whole family!" Michael Kutcher told Us Weekly. "Ashton and Mila are so excited to be parents." The rest of the Kutcher clan is pretty thrilled, too. "I have a 9-year-old myself, and a 4-year-old, and there's a 16-year-old in the family," he said. "We're so excited to expand the cousins of the new generation."

Michael also shared some Kutcher family traditions, saying, "My mom comes from an Irish Catholic background. She has 10 brothers and sisters, so we have a huge extended family. They're all around the same area," he explained of his Midwest-based relatives, noting that the group still gathers for major holidays. "We had 83 people in a farmhouse last Christmas, and Grandma cooked for everyone."

He added about his famous twin and fiancee Kunis, "Those two reunited after 14 years, and I think they were meant to be," he continued of the pair, who first met as costars on the sitcom That '70s Show. "It'd be like Ross and Rachel getting married [from Friends], like David Schwimmer and Jennifer Aniston getting married!"

Orange Is the New Black star Laura Prepon, who starred on 'That 70s Show' with Kunis and Kutcher back in the day, told Us Weekly on the red carpet at the Critics' Choice Television Awards, that the couple's baby news is "so awesome," and that "it's going to be great" when their baby arrives.

Prepon said about the famous couple back at the 25th Annual GLAAD Media Awards in May, "We grew up together, you know? It makes sense."

Prepon also spoke about her character Alex Vause coming back full force in season 3 of her hit Netflix series, saying ""It sucked because [show creator] Jenji Kohan and I wanted me to be in it more, but with the schedule, it didn't happen. I was so bummed out. But I handled it, so I'm in every [episode] in season three. It is so good."
