Just a few weeks ago, the old-school favorite performed a medley of his greatest hits, including "Nuttin' But Love," "Is It Good to You," "I Want Somebody" and "Now That We Found Love," at the 2011 BET Hip-Hop Awards.

He also appeared Oct. 8 at the Michael Jackson tribute concert in Cardiff, Wales.

"Man. I was just with Heavy D recently in London," tweeted Ne-Yo. "Had I known it'd be the last time I'd see him, I woulda told him he was truly great. RIP..."

Born Dwight Arrington Myers in Jamaica, the self-proclaimed "overweight lover" scored his biggest hits in the late 1980s and 1990s as part of Heavy D and the Boyz. The group's sophomore album, Big Tyme, and Nuttin' But Love in 1994 hit No. 1 on the U.S. R&B chart.

Heavy D posted his last tweet just 16 hours ago, writing, "BE INSPIRED!" About an hour before that, he had written, "SMOKIN JOE FRAZIER..RIP.. truly one of the best heavyweight champs that ever lived.. GODS SPEED,MR FRAZIER!"
