Three weeks after giving birth, Christina Aguilera gave her first post-baby interview this morning to Ryan Seacrest on KIISFm.

She admits that she is going “stir crazy” looking after her “stinky” son Max.

She says that he is giving her great inspiration for her next 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.”

She said Max was “doing amazing”. “He’s so incredible, it’s an unbelievable thing,” she said.

“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.”

She says another new thing for her is living with Jewish traditions with husband Jordan Bratman - including Max getting circumcised at his bris. “He did have a bris. It was a very sweet experience. We had close friends over to experience the bris with us.”

“We’re such a non-conventional couple we had penis balloons everywhere celebrating.”

She admits to being lucky compared to many other new parents. “I’ve a lot of great help around me. My mother-in-law gives a lot of great advice,” she said.

She also admitted Jordan is much more organized than she is. “My husband is the person who has all the questions [for the doctors], I’ll forget half of them by the time we get in there. He’s really good at staying on top of all the doctors’ stuff.”

She admitts that Paris Hilton did spill the beans about her pregnancy at a Hollywood club before she was ready to tell the world.

“People thought I was trying to keep it this big bad secret for so long. But really I just didn’t wan’t to address it at all. It really wasn’t this big sort of deal.

“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.”

Her first interview was to promote a new live DVD. She says she finds it strange watching the shows as she was already three months pregnant. “It’s so weir to watch the DVD back and know that I was pregnant with this little guy,” she said.
