Ryan Reynolds and Blake Lively are preparing to welcome their fourth child together—and their three kids have some feelings about it.

The Deadpool star opened up about expanding his family with Lively during a recent red-carpet interview with Entertainment Tonight.

“I’m very excited,” he told the outlet. “We’d have to be. You know, you’d have to be a moron to do this four times if you didn’t like it. It’s gonna be nuts, but we’re very excited.”

When asked how his kids—seven-year-old James, six-year-old Inez, and three-year-old Betty—feel about becoming big siblings, Reynolds answered, “They’re in. They love it. They’re ready.”

Lively announced her pregnancy by debuting her baby bump at the 10th annual Forbes Power Women’s Summit this past September. She made a glamorous appearance at the event, dressing her bump in a long-sleeved sheer minidress with a gold sequined chevron pattern. Accessories included a white headband, a white neck scarf, white platform pumps, and gold and sparkling ivory bangle earrings.

The Gossip Girl alum previously talked about parenting with Reynolds in a 2016 interview with Marie Claire. “Ryan had a nice, normal upbringing, and we want our kids to have the same normal life that we had,” she said. “We don’t ever want to rob them of what we had, because we’d feel really selfish.”

She also explained the struggles of having to shield her children from paparazzi. “I’d rather not have to deal with it at all, but we knew the lifestyle we were getting into, and while it’s hard … it’s another thing when it’s our child,” Lively said. “[James] didn’t have the opportunity to make a decision about what she wants.”
