The couple welcomed twins on Monday, she announced in an Instagram photo that showed Herjavec carrying them both in his arms.
“I never thought my heart could feel so full. We’re so in love with our little angels. Born at 7.44am and 7.45am 4/23/18,” the Dancing with the Stars pro, 41, wrote in the caption.
The couple did not reveal their “little angels” names.
The Shark Tank star, 55, is already a father of three children from a previous marriage.
The new parents first fell in love during Dancing with the Stars show rehearsals when they competed together on the 20th season in 2015. A year later, they wed in summer 2016.
As they prepared for their twins on the way, Johnson Herjavec revealed that her husband was “so excited” to be a father again.
“He’ll be really hands-on and he’s going to be great. He’s going to be such a good dad,” she said. “He’s already talking to them and telling stories.”
Adding, “I don’t know how we’re going to juggle the two, but [we’re] just going to go with the flow of it,” Johnson added. “I’ve been reading all these books but they make you crazy a little. I’m trying to be prepared, but I think you just have to wait and see.”
After three years with Herjavec, the dancer and BOD founder was excited to learn she would be a parent after doing the in vitro fertilization process.
“I’ve always wanted to be a mom and I wasn’t sure it was going to happen. It really is a miracle,” she told PEOPLE just weeks before her birth.
Adding, “It’s such an amazing blessing.”
