Meanwhile, Dwayne Johnson's new magazine photo shoot helps him hold the No. 1 spot on the chart, which ranks the most popular actors based on data from Facebook, Instagram, Twitter, YouTube and Google Plus.

Dwayne Johnson, Kevin Hart and Vin Diesel lead The Hollywood Reporter's latest Top Actors chart, ranking at Nos. 1, 2and 3 on the list dated Oct. 11.

The Top Actors chart is a ranking of the most popular actors on Facebook, Instagram, Twitter, YouTube and Google Plus, with global data provided by social media analytics company MVPindex. The chart's methodology blends social engagement on the platforms along with weekly additions of followers/subscribers. The latest tracking week ended Oct. 3.

Johnson leads for a 13th week (and third in a row) after posting one of the most-engaged-with photos of the week on Instagram by an actor, according to MVPindex, while Hart returns to his peak of No. 2, which he previously held on the ranking dated Sept. 13 (for more on the reasons behind his gain, see the Top Comedians recap).

Plus, Bella Thorne breaks into the top 10 for the first time after previously rising as high as No. 13 (Aug. 9).
