Rihanna's vocal producer Makeba Riddick told Billboard
that the recording of this song came right at the end of the sessions for Rated R
when "everyone was exhausted and creatively stumped." They asked Rihanna's manager Jay Brown if they could go home as they needed to recharge their batteries. He told them to stick around for one more day as that they had "just one more record" from Stargate that Ester Dean had started, which they believed could be really big. "She had the idea," Riddick recalled, "but we needed to revisit the hook and rewrite a verse, so there was still a lot of stuff to be done."
So, the exhausted Riddick sat with Rihanna to figure out how to finally the record. She said: "I was so tired, but I'm glad that I stayed, because 'Rude Boy' became the biggest song off that album and stayed at #1 for five weeks straight."
