in march 2010, a dispute then started between n-dubz and lethal bizzle, who claimed he had written and produced n-dubz's hit "i need you" for them and so should be acknowledged in the credits for it, with tulisa hitting back on twitter that "he's jus triena boost his status, ...wat an unbelievable loser!" and n-dubz later posted a video on their official youtube channel through twitter with the caption: "the proof we didnt steal s**t, we make our own hits!" of when he had sent them the finished song and when they had actually finished the song, implying that their version was over 2 months older than his.
