The 32-year-old singer is to start a two-year residency at Planet Hollywood Resort & Casino in Las Vegas this weekend.
Asked if she ever considers retiring, Spears told E! News, "I have thought about it, but I think right now is my time to perform and doing what I'm doing."
"If I happen to have another baby or something like that, I'd probably move back to Louisiana," she said. "I do miss Louisiana. I miss the people. I miss the food. I miss the way of life, how everything is really simple. There's no traffic like there is in LA. It's really nice."
