Who Is Amber Midthunder's Partner? Inside the 'Prey' Star's Guarded Love Life

Take a look at expert analysis about Who Is Amber Midthunder's Partner? Inside the 'Prey' Star's Guarded Love Life.

Despite keeping romantic declarations off magazine covers, Midthunder has never hidden her affection for her long-term partner, River Thomas. Thomas, a member of the Plains Cree First Nations, shares both creative and cultural alignments with the actor. Before entering the entertainment and modeling industries, Thomas built a reputation as a competitive collegiate volleyball player in Canada, playing for clubs such as the Briercrest Clippers.

Their connection surfaced publicly in late 2021 through understated social media appearances. Neither party staged a formal "relationship debut" photo op. Instead, digital followers noticed Thomas supporting Midthunder at select red carpet events and film industry gatherings. In August 2022, around the global launch of Prey, Thomas shared candid photographs alongside Midthunder, celebrating her milestone achievement with brief, sincere captions rather than performative statements.

Both individuals share Indigenous heritage, Midthunder is an enrolled member of the Fort Peck Assiniboine and Sioux Tribes, which forms a quiet backbone of their mutual support. They frequently appear together at community gatherings, Indigenous film celebrations, and cultural festivals across the American Southwest and Western Canada. Their bond reads to observers not as an industry power-pairing engineered for red carpet visibility, but as a grounded, real-world companionship.
