The duo took the stage together and debuted their single "Olvidame y Pega la Vuelta," followed by a sweet kiss, reported E! online.
Their new single is a remake of the famous Argentinian duo, Pimpinela's song. The song is about a lover who is asking her ex to forget about her-about her name, her face, her home-as she has learned to live without him, and she is moving on.
Post their performance, JLo, 47, presented her ex-husband with the Person of the Year Award.
