The American Idol alum, 33, and her soccer star husband, 31, welcomed their first child – daughter Harlow Monroe Harvey – on Wednesday (October 7), Us Weekly reports.
The newborn arrived at 9:37 a.m. “weighing in at a dainty but mighty 5.2 pounds and 18.5 inches long.”
As for the delivery, it was “the most intense and rewarding day of our lives,” the new mom shares.
“We are so grateful to be gifted this perfect little addition into our family,” she adds. “Can’t believe she’s finally here and we can’t keep our eyes off of her, especially when debating on whose nose she has. So many long nights, memories, and adventures to be made with this sweet little girl and looking forward to every minute.”
The proud new mom — who competed in Season 2 of American Idol in 2003 — wed the Vancouver Whitecaps soccer star in Palm Springs, Calif., in December 2014.
“Make sure to follow @emeraldduvjewelry to see what I’m up to today! I’m taking their Instagram over,” The Hills alum, 28, captioned the image with sons Camden, 3, and Jaxon, 17 months.
“In the mornings, now, I’m by myself with the boys,” the reality star-turned-designer recently told PEOPLE. “I like the mornings with the boys, so I don’t mind that.”
Kristin – who is expecting a daughter with NFL star husband Jay Cutler – says their elder son is all about daddy these days.
“It’s really cute,” she said. “He’s really into [football] now and he tackles Jaxon — which is not good — but I’ve been taking him to the games and he’s been having a lot of fun.”
As for her younger son, it sounds like he’s been picking up on mommy’s potty mouth.
“I swear a lot, so that’s been tough for me, but I’m trying really hard,” she admitted. “Camden said the F-word once. He said it like, ‘Mommy, why did you say f—?’ so he didn’t just say it for no reason. It really makes you catch yourself and make you be aware of what you’re saying all the time.”
“We are so excited about a son,” she gushed. “It’s great that we now have one of each. We do have a name and we have since before he was born. We have all of our children’s names picked out.”
As for having two under two, the country singer sounded optimistic.
“I think it will be OK,” she shared. “It will be an adjustment at first, but I have the help of my mama and sister so it will be OK the first couple months helping with Vivi and me nursing the little man.”
In the cute clip, the twins – who turn 5 next week – showcase their musical talents in front of their parents, including David Burtka. While enjoying breakfast, Gideon belted out the Star Wars theme and Harper sang Good Morning from Singin’ in the Rain.
Not to mention Harper’s ode to My Little Pony and Gideon’s new name for Facebook.
