Before welcoming the latest Irwin-Powell member, ET spoke to the Irwins earlier this year, where the family opened up about how their late patriarch, Steve Irwin, would feel about becoming a grandpa.
"He would've been a good, good grandpa. Yeah, he really would've been," the new mom said. "I don't think we would've ever seen our daughter. He would've just whisked her away into the zoo and it would've been perfect. But it is so nice that we'll be able to introduce her to her grandfather through all of the documentaries. It's really special."
