Colombian pop star Shakira dominated the seventh Latin Grammy ceremony in New York, scooping four awards.
Shakira last picked up a Latin Grammy award in 2002
The singer's Fijacion Oral Vol 1 picked up best album and best female pop vocal album. La Tortura won the award for song and record of the year.
Puerto Rican reggaeton duo Calle 13 scooped three prizes, including best new act, while Argentinian rock star Gustavo Cerati won two awards.
Shakira's album also won the Grammy for technical achievement.
The singer highlighted the plight of immigrants living in the US illegally who are trying to obtain citizenship while working without official documentation.
"All the Latino here, just as I did back then, they have a dream. All they need... is a visa for a dream," she said in one of her acceptance speeches.
Pop star Ricky Martin picked up the award for person of the year after he led a campaign against trafficking children for prostitution.
"To those traffickers, we are at war," he said to the audience.
Rapper and lyricist Residente was clearly surprised to beat Shakira in the best short film category - when the winner was announced he had been "looking for a beer".
Tego Calderon, a Puerto Rican singer who presented one of the awards to Calle 13, said he was glad to see the musical genre gain recognition.
"Reggaeton suffered a lot of prejudice at the start, just like hip hop, and now it is among the best music," he said.
Gilberto Santa Rosa, who won best salsa album, commented that his genre was also under-represented.
"Salsa has a merit and stature to have its own awards," he said.
