Madelaine Petsch has fans gushing over a lingerie snap of her as one even jokes that she’s showing “two good reasons” to watch Riverdale. The actress, who is best known for starring in the 2017-2023 series, stripped down to a plunging bra in a photo posted on Reddit two years ago, and feedback was definitely positive. The 2024-posted pic opened a gallery of snaps showcasing Madelaine in low-cut looks, with the user sharing them clearly a fan of her “perfect” curves. Madelaine gets most of her fan buzz on Instagram, where she is followed by over 22 milllion. Celebrities including former co-star Lili Reinhart and actress Sydney Sweeney follow her.

Madelaine Petsch Shows Her ‘Two Good Reasons’

Scroll for the photo. It showed the famous redhead shot relatively close up as she flashed her killer cleavage in a sexy getup.

Displaying her assets while in a scene, the 32-year-old dropped jaws in a cupped, deep-red bra with lacy embellishments and a busty finish. Rocking underwire and a push-up effect that further accentuated her chest, Madelaine hinted at her briefs while flashing her abs, completing her look with a discreet choker and full makeup.

Another image showed Madelaine in a plunging, plastic-effect, vinyl dress, with further snaps including her in a low-cut bustier, plus a yellow workout set. “Obsessed with her,” one fan replied. “She has perfect everything,” another said, also stating that they were a fan of Madelaine Petsch’s smile. “They are literally perfect,” a third said, with a fourth writing:

“Two good reasons I had to watch that whole show.” This wouldn’t be the first time Madelaine has stunned with her curves.

Stunning Sunkissed In Her Tiny Bikini

In these Instagram photos, Madelaine wowed in a dark blue bikini, enjoying a tropical beach setting as she overlooked turquoise blue waters. Laughing in one photo while wearing her shades atop her head, she offered a cleavage-baring shot in another, with one snap even peeking her rear. The photos were reposted on X in June 2025 and have now topped 3,000 likes. Madelaine isn’t the only TV star whose good looks will turn heads, though.

• Kaley Cuoco has flaunted her “nice Golden Globes” in a plunging red gown.
• Sydney Sweeney has been flashing her DDs in see-through underwear.
• Alexandra Daddario has highlighted her “awesome rack” shirtless while in a parking lot.
• And Jennifer Aniston is still a firm bikini favorite.

That Yellow Bikini Selfie

Madelaine works hard to maintain her enviable physique.

“I work out probably six days a week with my trainer LA Thoma Gustin. She’s incredible and really kicks my butt. I definitely love when we do circuit days because they always seem to go by way faster. She’s great at keeping my workouts interesting,” she told WhoWhatWear. In this selfie, the stunner showed off her fit abs and trim hips, showing off her curves in a plunging yellow bikini while snapping an indoor selfie.
