Nestor Alexander Haddaway (born 9 January 1965) is a Trinidadian-born German vocalist and musician best known for his 1993 hit single "What Is Love".
Born in Trinidad and Tobago, Haddaway moved to the Washington, D.C. area at the age of nine, where he grew up to the sounds of Louis Armstrong, which encouraged him to learn how to play trumpet at the age of 14. He attended Meade Senior High School. This eventually resulted in him forming his first group which he called Chances. Haddaway moved to Cologne, Germany in 1987 where he mostly worked in bars. Later, he formed his own company, Energy, which was involved in organizing fashion shows and photo-shoots.
Haddaway's break came in 1992 when he was signed by German label Coconut Records. His debut single "What Is Love" rapidly became popular in Europe, reaching number 2 in Germany and the United Kingdom. In Germany the single sold 900,000 copies. In the UK it was certified Gold for shipment of 400,000 units. It later reached number 11 on the Billboard Hot 100 and was certified Gold for shipments of 500,000 units. By the beginning of 1994, worldwide sales of "What Is Love" had already reached 2.6 million.
