Rihanna‘s highly anticipated album Unapologetic hit shelves yesterday and she dished to “On Air with Ryan Seacrest” about her rushed recording process.

Rihanna confessed that producers and engineers were in the studio until the wee hours of the night, every night until the very last minute to finish this album in time — all for perfection of every detail. This crazed process made it difficult for industry insiders to listen to her tracks until just before the deadline.

The sales numbers tell it all. Her sparkling reviews prove that hard work and little sleep pays off.
