I was just taking a look at some Twitter stats, and Lady Gaga, Justin Bieber, Katy Perry, and Rihanna are the top four most-followed people on Twitter at the moment. Apparently, Gaga is just 303 days away from 40 million followers, while Justin is 324 days away, Rihanna is 327 days away, and Katy is 412 days away - this trajectory being based off how many followers they gain per day. This means that within the next year, Rihanna is going to pass Katy on Twitter. And going off of how many followers she gains per day, I'm guessing she could someday pass both Justin and Gaga to become the most-followed person on Twitter. Not to mention that she's already extremely close to becoming the most-liked celebrity on Facebook.
