In an interview with The AP, the country star once again addressed controversy which began earlier this year after she was photographed looking "scary skinny".
Rimes explained: "[When I] was going through a divorce and I couldn't get out of bed... I gained 10 pounds, and then I lost 10 pounds because now I'm moving around and I'm working.
"I don't stop, and no one sees that [weight loss] actually can happen like naturally. It's a natural progression of life. It has to be some big deal and some issue. I'm glad there are people out there that are smarter than that and they don't buy into it."
Rimes was previously said to be hurt by the criticism about her physique and plans to release videos about her diet and fitness routines in order to showcase her healthy lifestyle.
Her husband Eddie Cibrian recently spoke out in support of Rimes, insisting that she is a "responsible eater" and is completely healthy.
