Spiedi are officially parents!

Heidi Montag and Spencer Pratt welcomed a baby boy named Gunner Stone on Sunday, October 1, Us Weekly confirms. Their little bundle was born at 3:06 p.m. He weighed in at 6 pounds, 12 ounces, and measured 19 inches long. He has blond hair and blue eyes, just like his daddy!

"We are so blessed to have a beautiful healthy baby boy. It was the hardest and most rewarding experience," Montag told the mag after delivery. "Officially the most lit day of my life," Pratt added.

The Hills co-stars began dating in 2006 and tied the knot in November 2008.

In typical over the top fashion, Spencer had $27K of crystals brought to the delivery room ahead of the birth!

Congrats guys!
