ebullient - adjective

The world was kept informed of Pavarotti's joie de vivre, his ebullient flirtations and his halfhearted struggle with his weight, which fluctuated between 250 and 350 pounds. At the peak of his career, he received more than 50,000 fan letters a year, and it was said that he never turned down a request for an autograph, a picture or a kiss.
