Mackenzie Phillips Keeps It Real About Her 'One Day at a Time' Beef

Mackenzie Phillips didn't hold back on Valerie Bertinelli's podcast this week, revealing that not everybody in the One Day at a Time family was actually family. She's talking about Richard Masur—and she wasn't shy about it. "He wasn't very nice," Phillips said flat out. That's the kind of thing you don't usually hear sitcom legends admit to in real time, which means something real went down.

One Day at a Time was peak '70s television, a show that somehow balanced family drama and laughs while actually saying something. You'd think a tight-knit cast would come with the territory. Apparently not always. Phillips and Bertinelli, both 66 now, were holding it down on the show together, but behind the scenes wasn't always smooth.

It's wild how these stories come out decades later—not as gossip, but as people just being honest about what the experience actually was. Phillips sharing this on Bertinelli's platform makes sense; they were allies on set, so this is less shade and more just acknowledging that Hollywood sets are human spaces where not everyone clicks. Sometimes the magic on screen doesn't match what happens off it.
