At only 21, actress Millie Bobby Brown is about to become a grandmother … to a donkey!

On this morning’s episode of The Drew Barrymore Show, Brown — a known animal lover —  announced that she and husband Jake Bongiovi’s pet donkey is expecting.

“We’re pregnant!” Brown excitedly told host Drew Barrymore, who exclaimed, “You’re a grandmother now!” before wondering how they found out the news.

“I went outside to the farm and Jake was in the garden. And I said, ‘Jake, doesn’t Betty look like she’s gotten into some food? She looks big,’” Brown continued. “I went out and I touched her tummy. And she was kind of looking at me and I was like, ‘You’re telling me something.’”

That’s when the Stranger Things star went to get her ultrasound machine, which she bought for the “stray dogs that come in pregnant.”

“Jake’s like, ‘Millie, you’re crazy.’ I was like, ‘Put more ultrasound gel on it. I need more connection.’ And then all of a sudden I’m looking at ribs,” she said, adding that she quickly called the vet to confirm her suspicions. “He came out and he goes, ‘She’s six months pregnant.’ So we are having a baby in June. I’m very excited.”

Brown, who married the son of rockstar Jon Bon Jovi in two wedding ceremonies last year, moved to a farm in Georgia with her husband. While Brown often documents her humble lifestyle filled with goats, lambs, chickens and dogs, she told Vanity Fair that she wouldn’t consider herself a “trad wife.”

“I’m not doing it for the aesthetic,” Millie said in the February interview. “I’m doing it because I love it. There are maybe some trad wives out there doing it because it seems wholesome, but it is not. If you’re not picking up horse shit or washing a cow with your bare hands, then that life is not made for you. At all.”
