Madelaine Petsch is a polka dot princess in daring plunge top as she serves up sodas to fans in LA

Madelaine Petsch proved once again that effortless summer style is her signature as she stepped out on California’s iconic Santa Monica Pier for a fun-filled fan event.

The Riverdale actress looked every inch the modern pin-up in a black polka dot halterneck top featuring a daring plunging neckline, which she paired with crisp white jeans and sleek black cat-eye sunglasses. Wearing her trademark copper-red hair in loose, glossy waves, Madelaine radiated Hollywood glamour under the Los Angeles sunshine.

The actress was joined by her former Riverdale co-star Vanessa Morgan and influencer Lars Gummer as the trio surprised fans while serving drinks from the Sparkling Ice Soda Shoppe.

Madelaine embraced classic retro dressing in her fitted polka dot top, accessorising with delicate jewellery and a fresh, natural beauty look.

At one point, she crouched down to speak with guests through the serving window, while another playful moment saw her joining Lars Gummer and Vanessa for selfies around the vibrant red pop-up installation.

Fans were also delighted to see Madelaine reunited with Vanessa, who played Toni Topaz opposite Madelaine’s Cheryl Blossom throughout the hit CW series.

Vanessa opted for an elegant all-white summer ensemble, pairing a lace sleeveless top with flowing trousers and oversized sunglasses as she greeted visitors alongside her longtime friend.

The event marked another public reunion for the pair, whose off-screen friendship has remained strong since Riverdale wrapped.

The sunny outing also comes just weeks after Madelaine sparked engagement speculation among fans after she was photographed wearing a striking diamond ring on her left hand.

The actress, who has been linked to rapper Tyga since late 2024 and made their relationship Instagram official in 2025, has not commented on the rumours, despite eagle-eyed fans questioning whether the sparkling jewel signals a new chapter in her personal life.

While Madelaine has kept her romance largely out of the spotlight, the couple have made a handful of public appearances together in recent months, fuelling interest in their relationship.
