The 41-year-old Dancing With The Stars veteran didn't reveal the names of their newborns.
Herjavec, 55, already has three children from a previous marriage.
The couple previously revealed to fans that they were expecting a son and daughter during their baby shower that was attended by fellow DWTS pro Cheryl Burke and hosted by pal and RuPaul’s Drag Race judge Carson Kressley.
Congratulations to the couple!
