The reason for the return? The 27-year-old singer was promoting her new DVD Back to Basics: Live and Down Under at a store in West Hollywood, People.com reports. Dressed informally in a flowy, low-cut shirt, Aguilera signed autographs for her fans. Earlier that morning, she told radio host Ryan Seacrest on his KIIS-FM show, “I'm very excited [about] this whole incredible thing that's taken place in my life, between the pregnancy and the birth. I've been brainstorming for the last nine months of my pregnancy. This next album will have a whole new me. A different me.” Of mommyhood and little Max, the artist told Seacrest, “It's a constant change. He's doing these incredibly cute things and incredibly stinky things!” Aguilera and her husband, music producer Jordan Bratman, married in November 2005 and welcomed their first child Jan. 12, 2008.
