Kym Johnson and Robert Herjavec welcome 'miracle' IVF twins

The first-time mum shared a sweet snap of her husband holding the newborns via Instagram.  

"I never thought my heart could feel so full," the 41-year-old wrote alongside the black-and-white photo. "We’re so in love with our little angels. Born at 7.44am and 7.45am 4/23/18."

In April, the couple announced they were expecting a boy and a girl via IVF. 

Herjavec, 55, also shared a close-up of the new arrivals to social media, where he revealed their names.

"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. May your dreams have no bounds and your spirit be strong."

Johnson met her beau on Season 20 of America’s Dancing with the Stars.

Herjavec, who appears as a judge on the US version of Shark Tank, is the father of three children from a previous marriage.

In January, Johnson told US Weekly that her hubby organised a baby shower for her at home in Australia.  

"[Robert] is the best. He spoiled me with a trip back home to Australia to see all my girlfriends," she told reporters at the G'Day USA event. "There was a little baby shower and saw my family and stuff so that was nice."

Johnson, who is currently based in the US, also hinted at her desire to raise her children in Australia and said her pregnancy was a "miracle." 

Congrats to the happy couple!
