Via Forbes: We looked at the celebrities with the most Twitter followers and Facebook fans and added the numbers together to come up with our ranking. Most of the top 10 also made our Celebrity 100 list, which is a ranking based on earnings and buzz.
Social networking can be a powerful tool for celebrities, and no one knows that better than Rihanna. The 24-year-old pop singer tweets a lot. She not only encourages her fans to buy her music and watch her videos, she lets them in on her daily life, posting photos of her friends and family.
Rihanna’s Facebook page is mostly a rehash of what she puts on Twitter, plus promotional material like plugs for her upcoming episode of Oprah’s Next Chapter. She has 59.6 million fans on Facebook and 23.8 million followers on Twitter, putting her at the top of our list of Social Networking Superstars.
Rihanna placed fourth on the Celebrity 100 with an estimated $53 million in earnings between May 2011 and May 2012.
