The couple, who were first romantically linked in October 2023, have been enjoying their engagement and have offered rare glimpses into their wedding planning.

Jason Segel's Most Notable Past Relationships and Dating History

Before finding his "forever" partner in Kayla Radomski, Jason Segel was involved in several high-profile and long-term relationships that often captivated the media.

Linda Cardellini (2001–2007)

One of Segel’s most significant early relationships was with actress Linda Cardellini. The two met on the set of the critically acclaimed but short-lived television series Freaks and Geeks in 2000. They dated for over six years.

Their eventual breakup is widely believed to be the primary inspiration for the screenplay of Forgetting Sarah Marshall, which Segel wrote and starred in. This film, which launched his career as a major box-office draw, explored the raw and often comedic pain of a difficult split.

Michelle Williams (2012–2013)

Segel's relationship with Oscar-nominated actress Michelle Williams was one of his most closely watched by the press. The pair dated for about a year and were often photographed together in New York.

Williams, who was the mother of Heath Ledger’s daughter, Matilda, brought Segel into a family dynamic, with the actor reportedly bonding well with Matilda. The relationship eventually ended due to the logistical difficulties of maintaining a bicoastal romance.

Alexis Mixter (2014–2021)

Segel’s longest relationship was with photographer Alexis Mixter. They began dating in 2014 and maintained a private but enduring partnership that lasted for eight years.

The couple called it quits in April 2021. Their split was amicable, with Mixter posting a heartfelt tribute to Segel on social media, praising their time together and wishing him well. This long-term commitment demonstrated Segel's desire for a stable, lasting connection, which he has now found with Kayla Radomski.

The Marshall Eriksen Effect: Why Fans Are Obsessed with Jason Segel’s Marriage

The intense public interest in Jason Segel’s love life, and the constant query about his "wife," is largely a product of his iconic role as Marshall Eriksen on the CBS sitcom How I Met Your Mother. For nine seasons, Marshall and Lily Aldrin (played by Alyson Hannigan) were the gold standard of on-screen relationships: a loving, stable, and deeply committed couple.

This fictional marriage set an impossibly high bar, making Segel's real-life pursuit of a partner a kind of cultural narrative. Fans saw Marshall’s journey to finding his soulmate, and now they are invested in seeing the actor achieve that same enduring happiness in his personal life. The engagement to Kayla Radomski is seen as a fulfillment of the "Marshall Eriksen promise"—a happy ending for the star who gave audiences one of TV’s most beloved marriages.

As Jason Segel continues his successful run on the acclaimed series Shrinking and prepares to marry Radomski, the focus shifts from speculation to celebration. The chapter of "Jason Segel wife" is about to be written, and fans are ready to cheer for the man who has finally found his real-life Lily.
