Héctor & Tito, also known as Los Bambinos, were a Puerto Rican reggaeton duo famous for their song "Ay Amor", featuring salsa singer Víctor Manuelle, which was the group's only charting song in the United States. They are widely regarded[by whom?] as one of the most influential and famous pioneering duos in the history of reggaeton. The duo caught the world's attention and expanded this genre globally, paving the way for artists like Daddy Yankee and Tego Calderón.[citation needed] They are also known for the songs "Gata Salvaje" (featuring Daddy Yankee and Nicky Jam), "Baila Morena" (featuring Glory and Don Omar) and "Amor de Colegio" (featuring Don Omar).
