Someone new is taking center stage: Kimberly Caldwell‘s a mom!

The American Idol alum welcomed her first child, a baby girl, with husband Jordan Harvey on Wednesday, Oct. 7, her rep confirms to PEOPLE.

Born in Vancouver, British Columbia, daughter Harlow Monroe Harvey arrived at 9:37 a.m., weighing 5 lbs., 2 oz. She measured 18.5 inches.

“We have been preparing most of 2015 for this day to bring our baby girl home to her princess nursery and today was finally the day,” Caldwell tells PEOPLE exlcusively. “My husband was so cute driving his girls home extra slow with extreme caution.”

She adds, “Our hearts are filled with overwhelming love and joy and soaking up every second of falling in love with baby Harlow.”

After finding out the sex and deciding on a name, the couple confirmed the pregnancy exclusively to PEOPLE in June.

“We are overjoyed to be preparing for the arrival of our baby girl,” the parents-to-be said.

In August, Caldwell, 33 — who joked her daughter was constantly “wiggling around” in her belly — and Harvey, a soccer player, posed for a series of pregnancy portraits to kick off the third trimester.

“It was so empowering to celebrate my bump and own my new curves. The best part was not having to suck in standing next to my husband and his abs,” Caldwell joked to PEOPLE.
