Miguel Ángel de Jesús, also known as Guelo Star, is a Puerto Rican reggaeton song-writer, composer, singer and occasional producer.
He began his music career writing and producing for other artists, establishing himself in the world of reggaeton and rap. In 2007, he joined forces with duos, Jaime Borges and Héctor Padilla (J-King & Maximan), and Randy Ortiz and Joel Muñoz (Jowell & Randy)and were taken on by the reggaeton producer of White Lion Records, Elías De León. They later became known as "Los Leones"
Their first studio album was released on June 26, 2007, and their single hit song No Te Veo reached #4 in The Billboard Hot Latin Charts.
As of 2008 Los Leones stopped performing as a group, however since this was a result of poor contract negotiation and not of any animosity within the group, no official break-up was announced. The 5 members are still signed by White Lion and still have a close working relationship.
