rihanna *As you know Rihanna is a bona fide hit maker.

In fact, she’s got 12 number one songs (singles) under her belt.

But interestingly, until this week, Rihanna had never known what it was like to have a number one album on the charts.

In her own “unapologetic” way, RiRi tweeted the news to her followers:

“Wait!! What the F*CK?! #UNAPOLOGETIC just debuted at #1 in America! My first number 1 album there! Thank you Navy, u deserve it.”

She could use some good news ’cause she was recently hammered by the press for the way she treated reporters traveling with her on her whirlwind “777″ world tour.
