Could Carrie Underwood be starting a country baby boom? If so, Kellie Pickler won't be participating. The "Little Bit Gypsy" singer isn't just waiting to have kids — she flat out doesn't want them.

"It's so exciting for Carrie," Pickler tells OK! Magazine, "but I don't want the responsibility of raising a human being."

At 28, Pickler is three years younger than her fellow "American Idol" star, and the two have become friends over time. She says shes fine just being Aunt Kellie, leaving no room for doubt about the future of her and husband Kyle Jacob’s household.

Musically, Pickler is working on a new studio album. Last summer she said she was in the middle of listening and writing for the new project. She tells OK! that writing with Jacobs ("More Than a Memory," "Dust") lets them connect on "an even deeper level."

Who’s the Best Country ‘American Idol’ Singer Ever?
