Liam Payne also defeated President Donald Trump for the title of "Male Top Ten Speaker"
Taylor Swift was named Twitter's "most influential" user in 2018, despite tweeting only 13 times a year.
Brandwatch, a social media analysis company, has published its annual list of Twitter's most influential influences today (28 November). Pop star "Look what you've done to me" went out on the women's list and got a "score of influence" out of 98 out of 100.
Former rival Katy Perry landed in second place with 96 points – before Kim Kardashian West, Demi Lovato and Ellen Degeneres.
On the men's list, Liam Payne was (somehow) named the most influential tweeter – defeated by President Donald Trump, Justin Bieber and Barack Obama.
The final score is said to be based on real engagement created by individual accounts – along with other Twitter metrics.
Like Swift – which last tweeted in June – and Bieber rarely broadcast on social media sites, these global stars are "capable of generating a huge amount of engagement" according to Brandwatch Data Journalist Gemma Joyce.
Last month, Swift ended political silence to support Democrats in the US mid-election – even though she chose Instagram via Twitter to invite her fans to vote.

Katy Perry slipped Taylor Swift and she was named the highest paid woman in the music. Forbes estimates that Perry received $ 83 million (£ 64.9 million) from June 2017 to June 2018, while Swift earned $ 80 million (£ 62.3 million) home.
In other news, Swift recently signed a new contract with Universal Music Group, which also provides money for other musicians.
