The singer, who filed for divorce from her husband Jordan Bratman last month, says women are often more powerful than they think.
"Every woman has the ability or the drive to do it all and have it all," Aguilera tells Redbook in its December issue.
"Men aren't as strong and capable as we are," she says. "We're machines."
Although Aguilera, 29, is going through a painful split, she says her son Max, who turns 3 in January, is always a priority as she negotiates motherhood and her career.
"My life is cyclical," she says. "First it's album time, then it's touring time. I'm not a 9-to-5 woman who has the same kind of lifestyle for years on end. I couldn't do it. I need the spontaneity, that thrill of change."
"This is what the cards have in store for Max," she says. "We put it into his brain early on that he's a traveling guy. He adapts well when we go from hotel to hotel."
Her pal and fellow mom Nicole Richie thinks her friend is very dedicated.
"It's very clear through Christina's music what a strong woman she is," Richie says. "But to watch her as a mother only sky-rockets the respect I have for her … Her dedication to Max is incredible."
