Rapper Pusha T revealed his involvement with the song in June 2016 and claimed that he had created the "I'm Lovin' It" jingle.[1] However, co-writers Batoy and Tortora, as well as several others involved with the jingle's creation, have disputed his claim.[1] Nevertheless, Pusha T's rap vocals do appear on the track for the first ad to air with the new hook and slogan; however, he was only paid on a one-time basis without royalties.[5]
