According to the outlet, the news comes as rumors were swirling that Mullally and Messing were having friction on the set. Eagle-eyed fans first noticed that Mullally stopped following Messing, 51, on Instagram. Soon after, she stopped following co-star Sean Hayes, 49. She still follows Eric McCormack, 56, but US Weekly reports that none of them follow her back.

Mullally and Messing have specifically seemed to keep their distance from each other while promoting Season 11 of “Will & Grace” on social media as well.
