The former Hills stars are yet to share a photo of their precious bebe, but that hasn't stopped the new father from gushing about his son.
Speaking with US Weekly he revealed that his son's birth was "officially the most lit day of my life."
"We are so blessed to have a beautiful healthy baby boy," Heidi added. "It was the hardest and most rewarding experience."
So how did the glamorous duo welcome their son into the world? In an extravagant room brimming with crystals, of course. Spencer took to Twitter to thank crystalarium for sending a whopping $27,000 ($34,000 AUD) worth of crystals to the couple for the birth.
"Shout out @crystalarium1 for dropping off $27,000 in crystals for the birth," he tweeted.
If that was just for the birth, we can't wait to see how the nursery turns out! Congratulations again to the happy couple.
