"[He is] amazing, incredible," the singer, 27, tells Entertainment Tonight. "He just lights up my whole world every day with his laughs and his smiles."
She reveals that Max has started crawling and is cutting his first teeth.
"He's a mover and shaker. He's just a smiley, happy guy. I really lucked out," Aguilera tells USA Today, adding that on Labor Day, she and husband Jordan Bratman, 31, took Max to the superhero exhibit at New York's Metropolitan Museum of Art for "his first museum experience."
Aguilera is looking forward to having more children – someday. "I definitely want to expand our family eventually, but for now, Mommy's going to work," she tells ET.
Aguilera, who just launched her first fragrance, Inspire, is prepping for her next album, due in 2009. It's full of "space sounds and futuristic things," she tells USA Today. "For this one, we're going into the future."
