Katarina Demetriades, the model and social media personality known as Katarina Deme, is engaged to Brandon Thomas Lee, Pamela Anderson and Tommy Lee’s eldest son. The couple announced the news on September 9, 2026, sharing photographs from their trip together and her engagement ring.
Demetriades already had a public profile through modeling and social media before the engagement. Alongside that work, she is studying philosophy at New York University, according to PEOPLE.
Katarina Deme’s Greek family background
Demetriades grew up in Los Angeles and has Greek roots through her father, businessman Jim Demetriades. Her parents are Jim and Nancy Demetriades; family records identify Katarina among their five children. Jim has publicly discussed his Greek ancestry, including in an interview with California newspaper The Sheet about his property investments in Mammoth Lakes.
Modeling and studies at NYU
Professionally, she uses the shortened name Katarina Deme. Her fashion work includes an InStyle editorial documented in the portfolio of Australian creative agency Artist Group, which credits stylist Rachel Wayman for the shoot.
Her current academic focus is philosophy at NYU. PEOPLE reports that she and Brandon now live in New York, having both grown up in Los Angeles.
From friendship to engagement
Demetriades and Lee were friends for years before they began dating in 2025. Lee, 30, proposed during a trip to Indonesia on August 29, 2026, PEOPLE reported in its exclusive engagement announcement.
They shared the news publicly less than two weeks later through a joint Instagram post. The photographs included a selfie showing Demetriades’s ring and an image of the couple kissing beside a beach bonfire.
