Why He's Sexy: Charles Kelley of Lady Antebellum's sex appeal begins onstage, as he opens his heart to revealing, emotional ballads and passionate pop-country party songs. He stands 6 ft., 6 in., but carries himself with the fluid motion of a figure skater. The married Kelley (sorry ladies) can fill out jeans and a tee or suit and tie and look like the outfit was made just for him. Mr. Kelley is Mr. Confidence.
