InTouch Weekly added a measure of confirmation to the story in an interview with the mother of Aguilera's new fiancé, Matt Rutler, 29.
"I don't know what their plans are," Kathleen Rutler told InTouch when asked if the couple would be moving from the West Coast anytime soon. "But when you have a baby, you're not planning on moving anywhere anytime soon!"
The news comes a week after Aguilera, 33, revealed her Valentine's Day engagement to Rutler, a production assistant in the film industry. They've been dating since 2010.
She finalized her divorce from first husband Jordan Bratman in 2011. They have a son together, Max, 6.
