New mommy Christina Aguilera talks only to ET about her new fragrance "Inspire" and the joys of mothering 7-month-old baby Max.

The vocal powerhouse, who was at Macy's in New York for the launch of her new scent, says the fragrance -- much like her upcoming album -- is "modern" and has a "high-fashion twist." The scent has elements of fresia, gardenia and tuberose.

Christina tells ET that baby Max is "amazing" and that she and hubby Jordan Bratman have plans to have more children in the future, but for now she's just focusing on work.

"He [Max] just lights up my whole world every day with his laughs and his smiles," she gushed.

Also announced today, Target plans to partner with Christina as the exclusive retailer of her latest album Keeps Gettin' Better - A Decade of Hits, a collection of the singer's most memorable songs.
