The 24-year old 'Diamonds' hitmaker is yet to achieve a number one album in the US and Brown feels she will achieve that with it, reported Contactmusic.
"We had our songs ready way beforehand, but we never stop recording. If we can record a month later, two months later, all the way to November 6th, we're never going to stop until that date. We're never content," he said.
Brown said Rihanna is following the same formula of music legends Elvis Presley, Frank Sinatra and the Beatles by releasing a new record each year.
"We're not creating anything new. She's always making music, because she loves it. So the strategy starts as soon as we get the idea for the next album. Are we going to release another album next year? I don't know.
"But it's just a natural thing for her. She'll say, 'I'm going to do a record', and the next thing I do is focus on going on tour" Brown said.
'Unapologetic' was released on November 19.
