The former American Idol finalist and her husband Jordan Harvey, a U.S. soccer player, welcomed daughter Harlow Monroe on Wednesday (07Oct15).

"We are so grateful to be gifted this perfect little addition into our family," the couple tells Us Weekly magazine. "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."

Caldwell and Harvey rang in 2015 as a married couple after tying the knot on New Year's Eve (31Dec14).
