Christina has always been a full figured latin girl at heart she's not obese at all what so ever she's a medium build 5 1.5" woman so she's supposed to be about 125lbs and is probably 140 or 12% over recomened weight which is heavy but not obese if she were 25% over the recomended weight for her height she'd be considered obese. a womans body gains and loses weight differently after she's had children and don't forget Christina's son Max is 4 years old and when she goes on tour she usually ends up underweight from all the choreography she does on stage
