Meet Oscar Piastri’s Siblings: Hattie Piastri, Edie Piastri, and Mae Piastri

Oscar Piastri, the rising Australian Formula 1 star driving for McLaren, has captivated the motorsport world with his exceptional talent, calm under pressure, and rapid ascent through the ranks.

Born on April 6, 2001, in Brighton, Melbourne, Oscar is of Italian-Australian descent through his paternal great-grandfather. While he keeps his personal beliefs private—his religion remains undisclosed—his public persona reflects a grounded, focused, and disciplined young athlete.

Raised in a car-loving household, Oscar is the son of Chris Piastri, founder of HP Tuners, and Nicole Piastri, known for her sharp wit and strong social media presence.

He grew up surrounded by automotive culture, with both of his grandfathers working as mechanics, which deeply influenced his early passion for racing. He shares a close bond with his three younger sisters—Hattie, Edie, and Mae—all of whom have garnered attention for their humour and unwavering support of Oscar’s career.

Oscar’s motorsport journey began with remote-controlled cars before transitioning to karting, where he quickly proved his natural skill. At just 14, his family made the significant decision to relocate to Europe, fully committing to his racing ambitions. Though details about his academic background are limited, he completed his schooling in Melbourne before moving abroad to pursue his dreams.

His rise through the ranks has been nothing short of historic: Piastri became the only driver to win the Formula Renault Eurocup, Formula 3, and Formula 2 championships in consecutive years, a feat that catapulted him to Formula 1 with McLaren in 2023.

Now 24, Oscar continues to impress on the global stage, while his family—particularly his sisters—have carved out their own fan base with their charm and authenticity.

Hattie Piastri

Hattie Piastri, the eldest of Oscar Piastri’s sisters, has quickly become a fan favourite in the Formula 1 community, thanks to her vibrant social media presence and sharp sense of humour.

Active on platforms like TikTok and Instagram, Hattie has built a devoted following by sharing funny, behind-the-scenes glimpses into life with her brother and showcasing her own unique interests.

One of her most beloved traits among fans is her passion for K-pop, particularly the Korean boy band TXT. A now-iconic moment in Piastri family lore involves Hattie leaving the Singapore Grand Prix early to attend a TXT concert—a decision confirmed by their mother, Nicole Piastri, during an episode of the Red Flags Podcast. Hattie later embraced the moment on TikTok, headbanging in front of a TXT poster, humorously owning her priorities.

Her charm was on full display during the 2025 Australian Grand Prix, where she was swarmed by fans at Albert Park, some playfully calling her their “favorite Piastri.” Social media lit up with fan encounters—one user captioned a selfie with her, “Just casually met my favorite Piastri today.” In another viral moment, Hattie joked about riding a tram covered in Oscar’s face, poking fun at his omnipresence in Melbourne and endearing herself even more to fans.

From viral dance videos—like the Piastri family’s TikTok rendition of Charli XCX’s “Apple”—to witty commentary and candid posts, Hattie has carved out her own spotlight. Much like her mother Nicole, known for her clever social media humour, Hattie has become a standout personality in the Piastri family, celebrated for her authenticity, relatability, and ability to make fans laugh.

Edie Piastri

Edie Piastri, one of Oscar Piastri’s younger sisters, tends to keep a lower profile than her sister Hattie but has still made a strong impression on Formula 1 fans with her appearances at key races—most notably during Oscar’s 2025 Spanish Grand Prix victory.

In a touching gesture, Oscar dedicated his fifth win of the season to Edie, signing a bottle of champagne for her and sharing a heartfelt moment in the paddock, as captured by McLaren’s official social media.

Fans across platforms quickly picked up on Edie’s presence in Barcelona, with some humorously suggesting that Oscar might be the “least cool” Piastri sibling after seeing her.

While Edie doesn’t share much publicly about her personal life, her consistent support at major events—such as the 2024 Japanese Grand Prix, where she attended alongside Hattie and Mae—shows her important role in her brother’s journey.

Edie’s quiet demeanour provides a contrast to Hattie’s more outgoing, social media-savvy personality, but her presence during pivotal moments highlights the strong bond within the Piastri family. A widely shared photo from the Japanese Grand Prix, showing Edie, Hattie, and Mae cheering for Oscar, captured the sisters’ collective pride and unity.

Though she may not seek the spotlight, Edie’s subtle, heartfelt support has resonated with fans who appreciate her calm, grounded presence—adding depth and warmth to the Piastri family’s growing public image.

Mae Piastri

Mae Piastri, the youngest of the Piastri siblings, remains the most private of the trio but has already sparked curiosity about her future. While she stays largely out of the spotlight, Mae has been seen supporting her brother, Oscar, at Formula 1 events, including the 2024 Japanese Grand Prix, where she joined her sisters, Hattie and Edie, in cheering him on from the paddock.

A September 2024 TikTok shared by Hattie offered fans an intriguing glimpse of what might lie ahead. In the clip, all three sisters were suited up in race car gear, with Hattie playfully hinting, “Oscar may not be the only driver in the family.”

Though Mae’s personal interests haven’t been publicly detailed, the post ignited speculation that she might share the family’s deep-rooted passion for motorsport—passed down from their father, Chris Piastri, founder of HP Tuners, and their car-loving mother, Nicole.

Despite her quiet presence online, Mae plays an important role in the Piastri family’s close-knit dynamic. Raised in a household where motorsport is second nature—her grandfathers were mechanics, and her father once served as Oscar’s personal mechanic—Mae has grown up surrounded by the same energy and enthusiasm that helped shape her brother’s career.

As she continues to appear at races with her sisters, fans are increasingly curious to see whether Mae will eventually step into the spotlight herself—whether behind the wheel, in the motorsport industry, or in a creative lane of her own.
