She gave birth on January 12 in L.A. with husband Jordan Bratman by her side, and she appears to be revelling in her new role.
The 27-year-old gushed: "He's completely changed my life."
She said recently: "I'm enjoying him every second. I can't stop staring at him, studying him. You can't believe you created this. Me and my husband couldn't be happier."
Still, she's keen to get back to work and has revealed 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 brainstorming for the last nine months of my pregnancy. This next album will have a whole new me. A different me."
Christina also has plans for more children, revealing: “We even look forward to possibly one day being open to adopt.”
