Asked what she did with her time off, the diminutive singer said she was happy to spend time with her son away from the cameras.
I cannot live in front of the camera 24 hours a day. I have to take breaks and stay connected with myself, I think that's important so that you can be your best on camera. I'm a mom, when the cameras go off I put on sweats and a t-shirt and I'm mom. He starts kindergarten in the fall so I'm excited about that ... I wanted, for myself, have a moment ... I've been on a really incredible journey the past six months, I feel revived and renewed.
Aguilera has also looked skinnier in Twitter photos from the set of the singing competition's fifth season, set to premiere September 23.

So much has been made of Aguilera's changing figure, that "Voice" co-coach Adam Levine came to her defense last October.
"The one thing about culture right now, celebrity culture particularly, is people feel like they can just say nasty things about other people, whether it's Christina or whether it's me," he said at a New York Q&A. "She gets a lot and it pisses me off. Of course I have her back and of course I defend her."
