Brandon Thomas Lee, the 30-year-old son of Pamela Anderson and Tommy Lee, is engaged to longtime girlfriend Katarina Demetriades. PEOPLE confirmed on September 9 that Brandon proposed during a trip to Indonesia on Saturday, August 29, capping off a relationship that began as a years-long friendship before turning romantic in 2025. Demetriades shared her own excitement on Instagram, posting photos from the proposal with the caption, "Meet my fiance 8.29.2026." The couple, both raised in Los Angeles, now live together in New York and are reportedly planning a wedding for late 2027.

Demetriades, 22, has close to 900,000 Instagram followers and previously dated musician the Kid Laroi from 2020 to 2023, she's currently studying philosophy at New York University. The two kept much of their early relationship private, with Demetriades joining Brandon at his younger brother Dylan Jagger Lee's wedding earlier this year marking one of their first prominent public appearances together.

Brandon has built a career in entertainment as an actor and Emmy-nominated producer, serving as CEO and head of production for And Her Son's Productions, the company he runs with his mother and brother. He produced the Netflix documentary Pamela, A Love Story, about Anderson's life, and executive produced her 2024 film The Last Showgirl.

The engagement comes just two months after Dylan, 28, married interior designer Paula Bruss in a ceremony in Saint-Tropez. Reflecting on watching her younger son marry earlier this year, Anderson told Vogue the milestone caught her off guard emotionally. She's expected to feel similarly as she now looks ahead to Brandon's wedding as well.
