Tharoor, who is among the first from Congress to have joined the Twitter bandwagon and the party's second most-followed leader after its president Rahul Gandhi on this medium, said "Rajnikanth was the only person who in his his first 24 hours on Twitter got 2 lakh followers.
"Given that Priyanka Gandhi has had only 12 hours on Twitter (so far) and she has got one lakh followers she seems to be on course to rival Rajnikanth. Looks like a new superstar on social media is born," he told PTI.
Significantly, she was yet to post her first tweet when the number of her followers crossed the one-lakh mark.
At the last count, she followed seven accounts, including the Congress' official handle and those of her brother and party chief Rahul Gandhi, Jyotiraditya Scindia, Sachin Pilot, Ashok Gehlot, Randeep Singh Surjewala and Ahmed Patel.
Priyanka Gandhi (47) and Scindia (48) took charge as AICC general secretary UP east and UP west, respectively, last week.
The Congress seems to have learnt its lessons from 2014, and has been scaling up its operations on social media platforms to challenge the BJP on a front which has been the saffron party's forte.
Earlier, Tharoor welcomed Priyanka Gandhi on Twitter, saying: "It was once a lonely furrow for a Congressman to plough glad to see @INCIndia stalwarts now all take to it with enthusiasm."
Rahul Gandhi has over 8.47 followers on Twitter to Tharoor's 6.75 million followers.
