These rumors about Miranda Lambert. Country music super star slamming reports that she's had a weight loss surgery since the punsking of the old fashion way diet and exercise. ABC's Sarah Heinz has the story.

She won big and rocked the stage of the country music awards. But Miranda Lambert debuted a whole lot more than her new duet with Kieth Urban that night. What really had tongues wagging was her spelled new figure. Noticeably slimmer then she was just six months earlier at the Kentucky Derby. Even her husband Blake Shelton couldn't help but twit: My wife is so hot. It's ridiculous.

I fluctuate all the time in my weight, and um, it's really annoying. At the time, she told E News and People Magazine it was all about diet and exercise. I have been working a lot, working out and drinking juice. But soon came the rumors that Lambert actually underwent weight lost surgery.

This morning, the white liar singer is calling the reports just that - lies. Writing on her blog: I wanted to set the record straight, I lost my weight the healthy and old fashioned way, watching what I eat and working out.

Safe weight loss is anywhere from one to two ponds a week, and she's a passive woman so it's absolutely within realistic expectations that she would have lost the weight as she claims.

Lambert says it's not about a scale, it's about how you feel and on November 10th, when I turned thirty, my skinny jeans were finally baggy. Mission accomplished.

She doesn't normally comment or speak to things in the tabloids. But this time, she felt it was important to set the record straight.
