Actress Lili Reinhart, star of the romantic comedy The Love Hypothesis, has been in a relationship with actor Jack Martin since 2023.

Reinhart’s new romantic comedy arrived on Prime Video on September 23, 2026, with the actress playing Olive alongside Tom Bateman as Dr. Adam Carlsen. Off-screen, Reinhart has described her relationship with Martin as the best relationship she has ever had.

Jack Martin is an actor who was born in Maryland and grew up in McLean, Virginia, according to People. He graduated from Georgetown University in 2019 and later trained as an actor at the University of Southern California’s School of Cinematic Arts and New York University’s Tisch School of the Arts.

Martin initially planned to study political science and pursue a career in politics. However, he changed direction after his first semester at Georgetown and decided to pursue acting.

He also built a large following on TikTok before establishing himself as a professional actor. According to People, Martin has more than 975,000 followers on the platform. He began creating comedy sketches and eventually signed with a manager and an agent.

Martin’s first major television role came in the science-fiction drama La Brea, where he played Josh Harris. The series ran for three seasons and concluded in 2024. He later appeared in Almost Friday TV and The Rookie, before making his film debut in Senior Prank in 2025.

His most prominent role to date is Josh Teitelbaum in the Hulu series Not Suitable for Work, created by Mindy Kaling and premiered in June 2026.

Reinhart and Martin first connected after she saw one of his videos making fun of Riverdale, the series in which she starred. Reinhart told Marie Claire in November 2025 that she subsequently sent him a direct message.

The pair were first publicly linked in April 2023 after they were photographed kissing outside Los Angeles International Airport. Martin later made their relationship Instagram official in July 2023 by sharing a series of photographs of the couple.

In September 2023, Reinhart and Martin made their first public appearance together at the Venice Film Festival. They attended a Giorgio Armani event and also went on a double date with actress Sydney Sweeney and her then-fiancé, Jonathan Davino.

Reinhart has generally kept details of the relationship private. In an interview with Cosmopolitan in July 2026, she said she had avoided discussing her relationship publicly to protect it, while describing it as the best relationship she had experienced.

The couple’s relationship has continued as Reinhart promotes The Love Hypothesis, which is based on Ali Hazelwood’s bestselling novel. The film also stars Tom Bateman and is available to stream on Prime Video.
