Chris Daughtry Reveals Incredible Transformation

"From 2010 to now," captions singer Chris Daughtry to a jaw-dropping then-and-now photo detailing his incredible weight loss and body transformation over the span of three years.

Sporting muscled arms, rock-hard abs and bulging muscles, the American Idol alum took to Twitter to show off all his hard work in the gym. The picture is quite a contrast to Daughtry in 2010, when the performer was significantly heavier.
