When you think of Friends, you think of the main squad. Phoebe, Rachel, Joey, Chandler, Monica, and Ross were our guides through the NBC sitcom's 10 seasons, and perhaps the best TV pals we'll ever make. However, Friends would have never reached the level of success it did without some additional characters dipping into their crew — many of whom had very famous faces.
It wasn't unusual for Friends to bring in big-name celebs to play love interests, siblings, and former classmates of the show's core gang. Sometimes these famous guest stars had real-life relationships with their on-screen co-stars. In other cases, they co-starred with the series regulars once again after Friends ended. And then, of course, there are the famous husbands (er, now ex-husbands) of the actresses who showed up for an episode.
With so many episodes of Friends to binge on Netflix, it can be hard to remember which famous faces showed up in the first place. This list is here to jog your memory — and help you revisit some of the series' most iconic moments.
