Robbie G.K.: From Stage Prodigy to Breakout Star of Queer Hockey Romance Heated Rivalry

Robbie Graham-Kuntz, professionally known as Robbie G.K. since 2023, was born on July 25, 1996, in Ontario, Canada, and raised in Port Credit. He began his professional acting career at age 13, landing the role of Kurt von Trapp in the Mirvish production of The Sound of Music at Toronto's Princess of Wales Theatre. This debut marked the start of a trajectory rooted in musical theatre, where he trained at Toronto's Etobicoke School of the Arts as a musical theatre major, honing skills in acting, singing, and dance.

G.K.'s theatre credits include ensemble roles in productions like Mamma Mia! and Joseph and the Amazing Technicolor Dreamcoat, as well as Willie Boulter in Anne of Green Gables: The Musical in Charlottetown, PEI, and Argonaut in the 2024 musical Medea in Hamilton, Ontario. Transitioning to screen work, he debuted on television in 2013 as Charlie in the Canadian teen drama The Next Step, appearing in 12 episodes. Subsequent roles included Joey in the 2015 horror film Antisocial 2 and Adam in the gymnastics-themed Full Out. In 2020, he gained notice for his recurring role as Tempo 3 in the Hulu sci-fi musical series Utopia Falls, a production blending music and dystopian themes that resonated with diverse audiences.

His filmography expanded with 2023 releases: Simon Carpenter in the thriller Marry F*** Kill and Joey in The House Call, the latter marking his first use of the Robbie G.K. moniker. In 2025, G.K. appeared in multiple television projects, including Riley in three episodes of Prime Video's comedy-drama Overcompensating, created by Benito Skinner, where he portrayed the love interest of a supporting character amid stories of closeted college life. He also guest-starred as Deputy Chris Whitley in an episode of the police procedural Sheriff Country.

The role cementing G.K.'s breakout status is Christopher "Kip" Grady, a smoothie-shop barista and art/history student in the Crave series Heated Rivalry, which premiered episodes on November 28, 2025. Adapted from Rachel Reid's Game Changers book series, the show centers on the queer romance between ice hockey rivals Shane Hollander and Ilya Rozanov , blending on-ice competition with off-ice attraction. Kip's introduction in episode three, involving interactions with hockey star Scott Hunter , sparked fan frenzy and viral clips, positioning G.K. as a scene-stealer. Originally auditioning for Scott with a mustache and mullet—"the most classic hockey bro look," as G.K. described it—director Jacob Tierney pivoted him to Kip, a decision that amplified his appeal.

Heated Rivalry has achieved viral popularity in LGBTQ+ media for its authentic portrayal of queer relationships in the hyper-masculine world of professional hockey, drawing community acclaim for visibility and representation. G.K., now 29, maintains privacy around his personal life, including relationship status, while pursuing interests like rugby with Vancouver and Charlottetown clubs. No major controversies are documented in available sources. His career trajectory underscores a rising talent bridging musical theatre traditions with contemporary queer storytelling, poised for broader impact.
