Bajan beauty Rihanna has reached another career milestone by hitting the 21 million followers mark on social networking site Twitter.

She took to her official page earlier this morning to thank her fans around the world for their unwavering support and wrote:

"Just left rehearsal and my #Navi is DEEPAH!!!!! Big up wunna self!!!! Welcome to the #RihannaNAVi and thank u #21milliNavi."

On June 18, the 'Where Have You Been' superstar told her beloved 'Navi' that she identifies with them and wants them to know she understands how it feels to deal "w/something heavy in ur life":

"#RihannaNAVi I see u, & I know that each 1 of u are dealing w/something heavy in ur life. Ur not alone! All we have is each other, LOVE!"

Although she isn't the star with the most followers on the site, she is starting to catch up to Lady Gaga, who has over 25 million Little Monsters checking up on her tweets, and Justin Bieber with his 23.6 million fans.
