The 44-year-old 'Now That We Found Love' performer died from a pulmonary embolism caused by deep leg vein thrombosis, TMZ reports. The tabloid website received the details from the Los Angeles County Coroner's Office.
His death was classified as "natural," which indicates that no foul play was involved. Besides the pulmonary embolism -- a blockage of one or more arteries in the lungs most often caused by blood clots that travel in from other parts of he body -- Heavy D suffered from heart disease.
A month before his passing, Heavy D performed at the 2011 BET Hip-Hop Awards, where he cruised through a medley of his best-known singles: 'Nuttin' But Love,' 'Is It Good to You' and 'Now That We Found Love.'
