This is Debra Messing.

Emmy-winner, Susan Sarandon's archnemesis, Grace Adler.

This is Megan Mullally.

Two-time Emmy winner, Nick Offerman's bae, Karen Walker.

We know and love them as besties on Will & Grace.

But now the rumor mill is kicking into high gear over claims that the two actors are feuding and that their animosity led to the end of the rebooted sitcom, which will wrap after its upcoming third season.

Messing and Mullally reportedly unfollowed each other on Instagram, which, as you know, is universal shorthand for "You're dead to me." A quick perusal of their 'Grams shows that they are indeed in the Unfriended Zone. But could ill will between the sitcom sisters have really put a kibosh on Will & Grace?

Sure, reports The Daily Mail. To its credit, the paper of questionable note did a deep dive in its attempt to legitimize this alleged feud. We're talking deciphering cryptic Instagram messages from literally months ago:

In May, Megan’s Instagram feed featured a lengthy post about people who 'use your success as ammunition against you.' And further back still, another appeared, stating: 'You can meet somebody tomorrow who has better intentions for you than someone you've known forever. Time means nothing, character does.' [...] Debra, meanwhile, uploaded a post a few weeks ago, urging fans to vote for Will & Grace for the Emmys, but failed to tag Megan.

The paper also collected fan reactions to the Great Instagram Unfollow of August 2019. It even went so far as to post, as evidence of the "frosty" relationship between Messing and Mullally, screencaps of a video from Eric McCormack's Instagram feed of a recent show taping.

The Daily Mail explains:

Sean Hayes was absent—for unknown reasons—and was replaced with a cardboard cutout as they welcomed the excited crowd. As Eric and Megan larked around at one side of the stage, Debra was seen shooting them a brief stare before heading over to hug the cardboard cutout of Sean.

What's the best part of this? The way they just glaze over the absence of Hayes, or how deep they're willing to read into a "brief stare"? It should be noted, however, that Messing commented on McCormack's post, directing him to "Send this to me!"

The rebooted Will & Grace was only supposed to be 10 episodes, so its conclusion after three seasons shouldn't come as too much of a surprise.

“We think of the Will & Grace reboot episodes the way Karen Walker thinks of martinis—51 is not enough, 53 is too many," creators Max Mutchnick and David Kohan and director James Burrows said in a statement. "That is why, after consulting with the cast, we all have decided this will be the final season of Will & Grace.”

We'd love to believe that Mullally and Messing are still pals and maybe just going through a rough patch, and perhaps it's not fair to blame the end of Will & Grace on their alleged feud. After all, the show's had a great run—twice. But if there is bad blood, here's hoping they repair their Insta-relationship.

And certainly their IRL relationship.
