José Fernando Cosculluela Suárez (born October 15, 1980) is a Puerto Rican rapper, singer and songwriter. In 2018, he was caught up in a controversy after fellow rapper Anuel AA released a diss track.

Cosculluela was born in Puerto Rico from Puerto Rican mother and Cuban father. He came from an upper-class family and was raised in the gated community of Palmas del Mar. At a young age, Cosculluela became interested in tennis and eventually played for his high school, Colegio San Antonio Abad. He also developed passions for golf and surfing.

At the age of sixteen, Cosculluela began producing underground mixtapes with his brother Jaime and his friends. After a few years of recording underground, popular reggaeton producer Buddha found out about Cosculluela's talents in a San Juan studio. Buddha was working with Latin hip hop producer Echo at the time. Buddha selected Cosculluela to replace rapper Tempo in the hip hop group Buddha's Family. Echo eventually signed Cosculluela to his label, Invasion Music.

Cosculluela gained international recognition with the hit single "Te Va Ir Mal" (feat. Getto) from the album Buddha's Family 2 distributed by Machete Music/Universal Latino. Soon after, Cosculluela began working with famed producers Gocho and Álex Gárgolas for multiple compilation albums. He also released a reworked version of his classic mixtape, "Este Es Mi Momento", in 2006.

After this, Cosculluela moved up in the ranks of reggaeton, appearing on such albums as Los Bandoleros Reloaded, Invasion, Gárgolas, Los Bravos, El Pentágono, El Pentágono: The Return, Los Brother, Talento de Barrio, and many more. Cosculluela is known to many as "El Príncipe del Verso" (The Prince of Verse) because of his exceptional lyrical abilities as an MC.

Echo was unable to get Universal Latino to release an album from any of his artists and only saw his compilation album "Invasion vol. 1" distributed. This caused Cosculluela to leave Invasion in 2007 and sign a recording contract with the renowned executive producer Elias De León and his influential record label White Lion Records. After struggling with record executives to set a release for his debut album, which was originally meant to be distributed on Sony Latin, and after various delays in 2009, Machete Music was pressured into releasing Cosculluela's hit debut album, "El Príncipe" (The Prince). It was released thanks to Cosculluela's friendship with Wisin & Yandel, who had a partnership with Universal Latino for their record label WY Records and were very influential at the company due to their immense success and popularity.

In 2009, Cosculluela released his first album, El Príncipe. The album was announced a year earlier and it was named after one of his nicknames. . It peaked at number three on the Billboard Top Latin Albums chart and spawned the hit singles "Na Na Nau", "Prrrum", and "Plaka Plaka". It also reached number eight on the Billboard Rap Albums chart. A few tracks were left out of the final production. El Príncipe was one of the most successful reggaeton albums of the year, becoming critically acclaimed due to its diversity in lyrics and style.

In 2010, Cosculluela released his first album called El Príncipe: Ghost Edition. This album was a review of his first album, but with 5 new tracks. These 5 tracks were Cuidau Au Au, Humo, Prrrum Remix ft. Nardo Ranks, and Another Prrrum Remix. They were performed with Wisin & Yandel, and the last track was De Noche y De Día feat. Yandel.
