Will & Grace” star Megan Mullally will reportedly not appear in several episodes of the series' final season amid rumors of an on-set feud with co-star, Debra Messing.

The series debuted the first of its 18-episode final run on Thursday, but TVLine reports that Mullally will not appear for at least two episodes later this season after taking a leave of absence.

Representatives for NBC had no comment when reached by Fox News. Mullally's reps did not immediately respond to a request for comment.

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.

McCormack, meanwhile, tried to downplay rumors of a feud rippling throughout the popular sitcom revival’s cast while speaking to Us Weekly in September. “It seems crazy. It is crazy!” he said. “I think people worried about that entirely too much.” He added: “The four of us get along like a house on fire, we always have.”
