[citation needed] A remix, released as part of G-Dragon's first live album Shine a Light on March 30, 2010, features American rapper Flo Rida.
The music video opens with G-Dragon in a lit up room a wearing black outfit, gloves, and shades.
When the chorus begins again, he dances in front of the same backdrop wearing a silver vest, accompanied by the same masked male dancers.
[3] G-Dragon was accused of plagiarism by Sony Music that "Heartbreaker" contained similarities to Flo Rida's "Right Round" (2009).
On September 21, 2009, Sisa Magazine, a news program on MBC, stated that officials from Sony reportedly sent YG Entertainment warning letters about plagiarism.
Sony's legal representative stated, "It was a hard decision for the music critics", however, they decided that there were similarities and accordingly issued a warning letter to the production company and its composers.
