The couple's little boy, Hudson Robert Herjavec, takes his middle name from his father, while ET has learned that his sister, Haven Mae Herjavec, takes her middle name from Kym's grandmother.
"Welcome to the world Hudson Robert Herjavec & Haven Mae Herjavec - it’s great out here ! May you always know love, peace, and grace in your lives," Robert captioned a sweet black-and-white photo of the twins. "May your dreams have no bounds and your spirit be strong."
Kym shared the first photo of Hudson and Haven on Instagram on Monday, just hours after giving birth. "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."
