Will Arnett's Girlfriend: The Complete Timeline Of His Relationships & New Romance With Supermodel Carolyn Murphy

Who is Will Arnett's girlfriend? The answer has shifted dramatically over the past 18 months, moving from a quiet, long-term partnership to a dazzling new high-profile romance. The story of the Arrested Development and SmartLess podcast star's love life is one of unexpected endings and fresh beginnings, playing out against the backdrop of Hollywood and the fashion world. For fans and followers, the rapid transition from one significant relationship to another has sparked intense curiosity. This comprehensive timeline and deep dive unpack everything we know about Will Arnett's romantic journey, from his split with Alessandra Brawn to his current relationship with supermodel Carolyn Murphy, including their first major red carpet appearances and what the future may hold.

The End of a Six-Year Romance: Will Arnett and Alessandra Brawn Split

The first major shift in Will Arnett's personal life came with the quiet dissolution of his relationship with Alessandra Brawn. After six years together and sharing one child, the couple reportedly ended their relationship in 2024. The news, initially reported by outlets like RadarOnline and later confirmed by People, described a split that was both amicable and intensely private.

A Look Back at Arnett and Brawn's Relationship

Will Arnett, 55, and Alessandra Brawn, 38, were first linked in 2019. Brawn, a former CEO of the clothing brand Chapel, represented a departure from the entertainment industry for the actor. Their relationship, while serious and family-oriented, was notably kept out of the relentless spotlight. They were occasionally spotted together at events like the Creative Arts Emmys in September 2019, but for the most part, they maintained a low-key existence focused on their family.

The decision to part ways after such a substantial period, especially with a child involved, signifies a major life change for the actor. Reports emphasized that the split was "quiet" and handled with mutual respect, a stark contrast to the very public nature of Arnett's previous divorce from actress Amy Poehler in 2016. This privacy was a hallmark of their partnership, and it continued through their separation.

The Co-Parenting Dynamic and Pregnancy Rumors

Adding another layer of complexity to this chapter is the well-being of their young child. Both Arnett and Brawn are reportedly committed to a healthy co-parenting relationship. Furthermore, swirling rumors, particularly from exclusive reports, suggested that Alessandra Brawn was pregnant around the time of or following the split. While these "exclusive details" were widely discussed, neither party has officially confirmed the pregnancy or its outcome. This rumor mill adds a layer of public speculation to what was otherwise a private family matter, highlighting the intense scrutiny celebrities face even when trying to keep things discreet.

The New Chapter Begins: Will Arnett and Carolyn Murphy

As the narrative of his split with Brawn settled, a new and dazzling plotline emerged. By September 2025, multiple reputable sources, most notably People magazine, confirmed that Will Arnett was dating supermodel Carolyn Murphy. The news, summed up in headlines like "Will Arnett has a new woman in his life" and "Will Arnett is now dating supermodel Carolyn Murphy," sent ripples through entertainment and fashion circles.

Who is Carolyn Murphy? The Model Behind the Headlines

To understand this new romance, one must look at Carolyn Murphy. She is not just a model; she is a bona fide supermodel with a decades-long career. Rising to fame in the late 1990s and early 2000s, Murphy became a staple on runways for top designers and a cover girl for countless fashion magazines. Her career represents the pinnacle of the modeling world, making her a significant figure in her own right, separate from her famous boyfriend.

Murphy's established fame and iconic status in the fashion industry create an interesting dynamic with Arnett, a star known primarily for comedy and podcasting. Their pairing bridges two very different yet equally powerful entertainment spheres.

The First Glimpse: Red Carpet Debut at the Golden Globes

The couple's relationship moved from rumor to confirmed reality with a stunning public appearance. In October 2025, Will Arnett and Carolyn Murphy dazzled on the Golden Globe Awards red carpet. This was not a casual date night; it was a deliberate, glamorous debut that announced their partnership to the world. Arnett, typically seen in more relaxed settings, was impeccably dressed, standing beside Murphy, who embodied classic Hollywood glamour. This single event served as the definitive proof for fans and media that this was a serious, public couple.

Their appearance was widely photographed and praised, with many noting the palpable chemistry and ease between them. It was a strategic and powerful way to introduce their union, leveraging one of Hollywood's biggest nights to control the narrative.

Cementing Their Status: London Film Festival & New York Fashion Week

The Golden Globes were just the beginning. The couple continued to solidify their status as a Hollywood power pair with subsequent public outings. They stepped out for their first red carpet event together since becoming a couple at the BFI London Film Festival. This choice of event—a prestigious film festival rather than a pure fashion or awards show—hinted at Arnett's roots in film and his continued relevance in that space.

Furthermore, they were spotted having a date night at New York Fashion Week in September. Attending fashion's biggest week, often seen as the domain of models and industry insiders, was a natural fit for Murphy and a clear sign of Arnett's integration into her world. These consecutive, high-profile appearances across different events (awards, film, fashion) demonstrated a pattern of intentional public coupling, moving swiftly from private dating to a shared spotlight.

Connecting the Dots: A Cohesive Narrative of Change

When we connect these key sentences, a clear and compelling story emerges. Will Arnett and his girlfriend, Alessandra Brawn, have reportedly broken up after six years together. This ended a long-term, quiet partnership focused on family. The news comes after the couple was spotted attending his... [events, implying a gradual cooling off before the official split]. Following this, Will Arnett is dating model Carolyn Murphy following his split. The transition, while seemingly rapid in public perception, likely had a private timeline. People confirmed the two are dating on Sept [2025], and within months, they were dazzled on the Golden Globe Awards red carpet.

This swift pivot from a six-year relationship with a fashion executive to a very public romance with a supermodel is the core of the fascination. It represents a significant shift in Arnett's personal life—from a more private, family-centric chapter to one that is undeniably glamorous and in the public eye. The age gap (Arnett is 55, Murphy is 52) is minimal, and both are established figures in their respective fields, suggesting a meeting of equals rather than a fleeting celebrity fling.

What This Means for Will Arnett's Future

With this new relationship comes inevitable questions about Arnett's future. The persistent rumor of Alessandra Brawn's pregnancy during or after their relationship adds a layer of potential complexity. If true, Arnett could be going to be a father again, a life-changing event that would coexist with his new high-profile romance. How he navigates fatherhood, co-parenting, and a very public new relationship will be closely watched.

For Carolyn Murphy, dating one of Hollywood's most likable and busy actors is a new venture. Her own career, while perhaps less frenetic than in her 1990s heyday, remains powerful. The synergy between her fashion world and his entertainment world creates a modern celebrity couple dynamic.
