 Minaj expressed excitement when approached to collaborate on the song , and she had contributed 32 bars to the track . Her main inspiration behind working on the track was the possibility of meeting Jay @-@ Z , with whom she was obsessed since a young age . According to her , she literally couldn 't have a conversation without quoting a line by him , and it was a dream come true to collaborate with the artist . Minaj had recorded her lines around four months before the lyrics finally appeared on the song . Minaj described both Jay @-@ Z and West as " icons " , and stated that she was blessed to be working with them . In an interview with Rap @-@ Up , Minaj mused " never in a billion years would 've thought that I would 've not only been on a song with one of them but both them " .
