Christina AguileraChristina Aguilera has said she’s keen to get back to work after giving birth to son Max last month.

She told Ryan Seacrest’s KIIS-FM radio show recently: “I’m so going stir-crazy in the house.”

“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. A different me. I’m very excited! I’m so inspired.”

Christina launched a DVD of her Back to Basics tour earlier this week and added that it was strange to see herself performing with a baby bump now that the baby is here: “It’s so weird to watch the [Back to Basics] DVD and know I was pregnant with this little guy in my belly. It’s amazing.”
