Baby Speidi is here: Heidi Montag and Spencer Pratt, who rose to fame as The Hills love-to-hate-them villains, have welcomed their very first baby.

Montag, who first announced her pregnancy in April, gave birth to a boy the couple have named Gunner Stone, according to Us WeeklyLittle Gunner weighs in at 6 pounds, 12 ounces and has blond hair and blue eyes.

"We are so blessed to have a beautiful healthy baby boy," Montag told the site. "It was the hardest and most rewarding experience."

Pratt added meeting his son was "Officially the most lit day of my life."

“The look on [Heidi's] face, I can’t even describe it. She was literally glowing,” Pratt said. “I thought she was about to say she made muffins or banana bread.”

“Heidi said, ‘I’m pregnant,’ ” he added. “I was like, ‘Whoa, that’s way more exciting than banana bread!’”

“I started crying, and he embraced me,” Montag added, but noted pregnancy came with its complications — namely, morning sickness.

“Every time I feel awful, I remember why and I’m just euphoric,” she said. “It’s so fulfilling, and I’m mostly just grateful. I’ve been with the love of my life for 10 years, and now we’re starting our own family.”

Montag joins former Hills co-stars Whitney Port and Lauren Conrad, who both recently gave birth to their respective first kids.
