Body after baby: Christina Aguilera in LA yesterday; the singer just days before giving birth

The pop star made her first public appearance since welcoming her first child to promote the release of her new DVD set Back to Basics: Live and Down Under in LA yesterday.

It appears she welcomed the change of scenery, with the star admitting: "I'm so going stir-crazy in the house."

In a radio interview prior to the appearance, she gushed about her "incredible" son and said she is already inspired to write a new album.

"This whole incredible thing that's taken part in my life, between the pregnancy and the birth, I've got so much to be inspired about and so much in my life to write about.

"I've been brain-storming for the last nine months, actually. This next album will have a whole new me, so there's a lot to look forward to."

The 27-year-old says she and husband Jordan Bratman reveling in parenthood: "It's still the first couple of weeks, every week something new happens.

"It's constant changing and he's constantly changing and doing these incredibly cute things - and stinky things."

The singer was also asked how she felt about Paris Hilton announcing her pregnancy to the world before Christina herself had confirmed it.

Paris made the comment while addressing a crowd at a Hollywood club, which left Christina and her friends looking rather shocked.

Christina says now: "Paris did kind of jump the gun a little on it, so she became the official announcer at a club appearance.

"It was funny. I laughed about it. I was a group of friends ad we all looked at each other a little surprised but we laughed it off.

"It was actually cute, she did it in a very sweet way so it wasn't in a kind of tattle-on-you kind of thing."
