You remember her. The character who basically stomped into the Forman basement and flipped the social hierarchy on its head. If you've been rewatching the series on Peacock or catching reruns, you've probably found yourself wondering who plays Rhonda on That 70s Show. Her character, affectionately and somewhat crudely known as "Big Rhonda," was a force of nature. She wasn't just a punchline; she was the girl who actually managed to make Fez—the group's perpetual outsider—feel like the coolest guy in Point Place.
The actress behind the denim vest and the aggressive charm is Cynthia Lamontagne.
It’s kind of wild when you look at her career. She wasn’t some newcomer found at an open casting call. By the time she stepped onto the set of That '70s Show in 2001, she was a seasoned pro. She’d already been in huge projects. But there was something about the way she leaned into the physical comedy of Rhonda that made the role iconic. She took a character that could have been a one-dimensional "tough girl" trope and made her genuinely likable, even when she was threatening to beat up the rest of the gang.
Why Cynthia Lamontagne Was Perfect for Rhonda
Casting is everything. Seriously. If you get the wrong person for a role like Rhonda, the jokes feel mean-spirited. But Lamontagne had this specific energy. She played Rhonda with a total lack of insecurity. Think back to her first appearance in the Season 4 episode "Eric’s Hot Cousin." While the rest of the girls were worrying about their hair or their boyfriends, Rhonda was just... there. Existing loudly.
She appeared in six episodes total. That’s it. It feels like way more, doesn't it? That is the hallmark of a great character actor.
Lamontagne understood the assignment. She worked with the writers to ensure Rhonda wasn't just a bully. She was Fez’s first real, consistent romantic interest who actually liked him for his weirdness. Their chemistry was bizarre but somehow the most wholesome thing on the show at the time. While Jackie and Kelso were busy cheating or screaming, Rhonda and Fez were just busy being "frisky."
The Career of the Woman Who Plays Rhonda on That 70s Show
If you think you recognize her from somewhere else, you’re probably right. Cynthia Lamontagne didn't just disappear after Rhonda left the basement.
Before she was wearing 1970s polyester, she was in one of the most famous comedies of the 90s. She played Foxy, one of the women in The Birdcage (1996). If you haven't seen it lately, go back and watch—she’s there alongside Robin Williams and Gene Hackman. It’s a completely different vibe from Rhonda, which just goes to show her range.
She also had a stint in the Joss Whedon universe. Fans of Buffy the Vampire Slayer might remember her as Lydia, a member of the Watcher's Council. Again, totally different. No gum-chewing, no tough-talk, just a buttoned-up British academic type. She also popped up in Frasier, Dharma & Greg, and Veronica Mars.
Honestly, her filmography reads like a "Best of" list for 90s and early 2000s television.
- The Birdcage (1996) - Foxy
- Austin Powers: International Man of Mystery (1997) - One of the Fembots (Yes, really!)
- Forgetting Sarah Marshall (2008) - Female Bartender
That last one, Forgetting Sarah Marshall, was actually her final credited role before she stepped away from the limelight. She played a bartender at the Hawaiian resort. It was a small part, but if you look closely, you can still see that "Rhonda" spark in her performance.
The Mystery of Rhonda’s Departure
One of the most frequent questions fans ask, aside from who plays Rhonda on That 70s Show, is what happened to her? One minute she’s Fez’s girlfriend, and the next, she’s just... gone.
In the world of the show, she and Fez broke up off-screen. It was a classic sitcom move. Shows do this all the time when a guest star's contract ends or the writers want to take a main character in a different direction. Fez went back to being the desperate, girl-crazy guy we knew, and Rhonda presumably went on to be the coolest girl in whatever school she ended up in.
There was a rumor for a while that she left because of a dispute, but there’s zero evidence for that. In reality, That '70s Show frequently rotated guest stars to keep the basement dynamic fresh. Lamontagne moved on to other projects, and the show moved on to Fez’s next obsession.
Where is Cynthia Lamontagne Now?
Unlike many actors who stay in the "biz" forever, Cynthia Lamontagne chose a different path. After 2008, she basically retired from acting. You won't find her on Instagram posting "throwback Thursday" photos from the set. She’s stayed incredibly private.
In an era where every minor celebrity has a podcast or a reality show, there’s something kind of respectable about just doing the work, creating a legendary character, and then walking away to live a normal life. She married Aaron Zelman (a writer and producer known for The Killing and Bloodline) in 2006.
The Lasting Legacy of Big Rhonda
Why does this character still resonate? Why are we still searching for the actress decades later?
It’s because Rhonda represented something rare for 2001 television. She was a "big" girl who wasn't depicted as miserable. She wasn't trying to lose weight. She wasn't the butt of the joke because of her size—usually, the joke was on the guys because they were intimidated by her. She was confident, sexual, and took what she wanted.
When Fez tried to use his "foreign" charm on her, she didn't swoon; she challenged him. That dynamic was hilarious because it flipped the script. We loved Rhonda because she was the only person who could truly handle the gang's nonsense.
How to Find More of Her Work
If you’re looking to see more of the woman who plays Rhonda on That 70s Show, your best bet is to dive into late-90s cinema.
Check out Austin Powers. It’s a "blink and you’ll miss it" moment, but knowing that the tough-as-nails Rhonda was once a sleek, silver-clad Fembot is the kind of trivia that makes being a TV nerd fun.
If you want to revisit her best moments on That '70s Show, these are the essential episodes:
- Eric's Hot Cousin (Season 4, Episode 14) - Her debut.
- An Ice Cream Truck One (Season 4, Episode 15) - The relationship with Fez kicks off.
- Donna's Story (Season 4, Episode 16) - Classic Rhonda interaction with the rest of the girls.
Taking Action: Beyond the Basement
If you’re a fan of character actors like Cynthia Lamontagne, the best thing you can do is support the preservation of physical media. Streaming services like Netflix and Peacock drop shows constantly. To ensure you can always find out who plays Rhonda on That 70s Show, consider picking up the series on Blu-ray. It’s the only way to guarantee these performances don't disappear into the "digital void."
Also, if you're writing your own scripts or creating content, take a page out of the Rhonda playbook: write characters who subvert expectations. The world doesn't need another generic "tough guy" or "mean girl." It needs more Rhondas—people who are unapologetically themselves, even when they’re wearing a questionable amount of corduroy.
