Nicole Kidman and Keith Urban attended the Academy of Country Music Awards -- and the couple couldn't help but gush about their baby girl, Sunday Rose!

"She loves it," Nicole says of her daughter spending time in Sin City. "She's been out and about. I think because it's so colorful. It's big for her. She lives on a farm. This is a big city."

The "Australia" actress also praised Urban's new album, "Defying Gravity," saying, "Sunday and I are his biggest fans. We love it." Urban added, "[They're my] biggest inspiration too."

Sunday Rose, 9 months, hasn't started speaking yet, but mom Nicole said the baby is very chatty! "There are lots of coos and grunts," Kidman reveals. "She's very vocal."
