The 'Fixer Upper' stars' announcement of their latest pregnancy gave them a boost on the chart, which ranks the most popular TV personalities based on data from Facebook, Instagram, Twitter, YouTube and Google Plus.

News of Joanna Gaines’ pregnancy bumps the Fixer Upper star to No. 1 on The Hollywood Reporter’s Top TV Personalities chart dated Jan. 17, followed closely by her husband, Chip.
