The insider says that Nic’s non-stop flirt fest with the makeup artist, who is paired with Michael, is one of the reasons Cyrell and Martha come to blows later in the season.

“Cyrell just loses it completely,” adds our source.

“She blames Martha for the whole thing and accuses her of trying to steal her husband, but everyone on set knows it‘s Nic who’s the one trying to woo Martha away from Michael.”
