"We took various 'most successful' and 'most followed' to build our list of celebrities across acting, sport, music, and TV personalities. We then filtered this by the number of followers to give ourselves a top 100 most followed list," ICMP said in a statement.
"We then ran their Instagram and Twitter handles through IG Audit and Sparktoro's fake Twitter follower's tool to measure what percentage of their following was actually real," it added.
As Facebook-owned photo-messaging app Instagram continues to grow, influencer marketing has emerged as a major trend in 2019 that earned influencers the highest amount of money for paid posts to date.
Attaining the 19th spot, Priyanka made it to the list along with Indian cricketer Virat Kohli who sits on the 23rd rank. While Priyanka Chopra Jonas charges $271,000 per post, Kohli charges $196,000.
