Aside from currently being ranked at the No. 4 spot of people most followed on Twitter, Rihanna has landed a spot on TIME Magazines Top 100 Most Influential People In The World list.  She and Adele are the only 2 mainstream music artists who have been given the recognition on this list.  

Here is what TIME Magazine had to say about why they gave Rihanna the honor of being put on the list:

"She's one of the coolest, hottest, most talented, most liked, most listened to, most followed, most impressive artists at work today, but she does it in her own stride.  She works hard, very hard.  She gives to her fans, friends and foundation not just herself but her energy and spirit."
