Christina Aguilera feels refreshed after weight loss

Pop star Christina Aguilera is feeling refreshed and light after shedding 30 pounds.

The 32-year-old 'Your Body' hitmaker said she is happy to have got some time to spend with her son Max, reported Contactmusic.

"It's a lot of stagnant energy sitting in a chair for three years in a row. I got to have, finally, a break and spend some time with my son," Aguilera said.

"Being able to breathe and have time away outside of the camera and get to the nitty-gritty of all things real and personal (allowed me to come) back refreshed," she added.

The 32-year-old star reportedly banned dairy and other high calorie food from her diet to lose weight.
