Christina Aguilera Talks Shedding Her Baby Weight

Since giving birth to son Max two months ago, Christina Aguilera has undergone a fierce weight loss regimen.

As it turns out, nursing her little boy is the real secret behind newly slimmed-down mommy Christina.

“I think they say that when you’re breast feeding, you know, your weight kind of slims down. It’s a little easier,” Christina told Access Hollywood. “It’s like a workout within itself. It’s very tiring actually and you find yourself snacking more often.”

But before Max came, a four-months pregnant Christina (who kept her news a secret at the time) posed as a Hitchcock heroine for a new ad campaign for the Stephen Webster jewelry line.

Christina appeared as a classic femme fatale in the shoot, donning a little black dress, leopard skin belt, stilettos and fishnet knee-highs.

“Where we took the ads I think, is a really original place. It was fun experimenting with that,” Christina said. “Some of the Alfred Hitchcock movies we drew inspiration from for the ads were… ‘Rear Window,’ [and] ‘Dial M for Murder.’”

Christina and Stephen are long time friends. He has designed many pieces for her including her wedding ring.

In fact, the designer confessed that Christina is the muse behind his latest unconventional collection.

“I probably consistently work with her more than anyone else,” he told Access.
