As she celebrates today’s release of her new DVD set Back to Basics: Live and Down Under at Best Buy stores, new mom Christina Aguilera phoned into Ryan Seacrest’s KIIS-FM radio show this morning.

She revealed how her newborn son Max has inspired her to write her next album and also recalled her experience being pregnant.

“It’s so weird to watch the [Back to Basics] DVD and know I was pregnant with this little guy in my belly,” she said. “It’s amazing.”

When asked if her experience being pregnant will play a role on her next album, she said, “I’m very excited! I’m so inspired.

“This whole incredible thing that’s taken place in my life, between the pregnancy and the birth….

“I’ve got so much in me to write about.

“This next record, I want to have a lot of fun with it. I’ve been brainstorming for the last nine months of my pregnancy.

“This next album will have a whole new me,” she added. “A different me.”

Aguilera, who recently sold her baby pictures for $1 million, also talked about Max’s bris, the traditional Jewish baby naming and circumcision ceremony held at her house shortly after she and husband Jordan Bratman welcomed their son.

“I’m not Jewish, my husband is,” she said. “I really had no idea about the bris….

“It was a very sweet experience,” she added. “We had a lot of close friends come over and experience the bris with us.”

Joking, she added, “We’re such a non-conventional couple … we had penis balloons everywhere!”

Seacrest asked her if she felt Paris Hilton let the cat out the bag by announcing her pregnancy before Aguilera herself has confirmed it.

“Um, you know, not really,” she said. “People thought I was trying to keep it this big bad secret.

“Really, I just didn’t want to address it.

“Paris did jump the gun on it … she became the official announcer at a club appearance.

“It was funny,” she said. “I laughed about it.”
