Olivia Munn’s 1 a.m. Engagement: James Marsden’s Role in a Serendipitous Proposal Olivia Munn’s 2023 engagement to comedian John Mulaney was deeply tied to the unexpected energy of her longtime friend James Marsden. The event unfolded during Marsden’s 50th birthday celebration in September 2023, a gathering that became a pivotal moment in Munn’s personal life. Munn, who has been a guest on Marsden’s comedy series Your Friends & Neighbors since its Season 2 debut in April 2023, recounted how Marsden’s presence in her life had long been a source of comfort. The pair had known each other since childhood, with Munn growing up in Oklahoma and Marsden’s younger sister being a friend. Munn remembered a high school memory when Marsden took her and his little sister out for dinner and ice cream, a gesture she called “really sweet.” Marsden’s influence extended beyond their shared past. During a difficult period in Munn’s life, when she was recovering from surgeries for breast cancer, Marsden’s support helped her regain confidence. “I wasn’t really feeling like myself,” Munn said, explaining her decision to attend Marsden’s birthday party. “I wanted to get dressed up, do glam, and see how I felt.” The event, held at Los Angeles’ historic Sheats–Goldstein Residence, became a catalyst for a life-changing moment. Munn described the evening as “so serendipitous.” Mulaney, who had been in a relationship with Munn for years, had been considering a proposal but needed the right moment. Marsden’s birthday party provided the perfect setting. “John was like, ‘This is the best time to propose to Olivia,’” Munn recalled. “My husband was like, ‘She’s going to be all dressed up, she’s going to feel really great.#james_marsden #your_friends_and_neighbors #olivia_munn #john_mulaney #sheats_goldstein_residence
