The Evolution of Milo Greene: From Indie Darling to Musical Trio

Robbie Arnett is perhaps best known for his foundational role in the indie-pop band Milo Greene. Formed in Los Angeles, the band was unique for its democratic songwriting process and the fact that all four original members—Arnett, Graham Fink, Marlana Sheetz, and Andrew Heringer—shared lead vocal duties. The band's name, Milo Greene, was originally conceived as a fictional booking agent, a clever entity to represent their collective creative output.

The Band's Discography and Sound

The band’s self-titled debut album, *Milo Greene*, was released in 2012 and quickly established them as an indie darling with a dreamy, cinematic sound. Their music was so evocative that it was frequently featured in major films and television shows, showcasing Arnett’s talent as a songwriter and instrumentalist.

Their second album, *Control* (2015), marked a shift toward a more synth-driven, polished pop sound. However, their third major release, *Adult Contemporary*, released on September 7, 2018, is considered their most recent full-length project. The album showcased a mature, more reflective indie-pop style. While the band has become less active in recent years, the foundation of Arnett’s artistic identity remains rooted in the collaborative, melodic nature of Milo Greene’s music.

The Ultra-Private Relationship with Elizabeth Olsen

Robbie Arnett and actress Elizabeth Olsen have become a prime example of a successful, low-key Hollywood couple. They first met in 2017 while on vacation in Mexico through a mutual friend, and their relationship quickly blossomed away from the public eye. Their commitment to privacy is a defining characteristic of their romance, which is a conscious choice given Olsen’s high-profile career as a central figure in the Marvel Cinematic Universe.

A Secret Wedding and Public Confirmations

The couple became engaged in 2019, but the details of their marriage remained a mystery until Olsen casually referred to Arnett as her "husband" during a 2021 interview. It was later confirmed that they had a secret wedding, likely a small, intimate ceremony, further solidifying their preference for keeping their most important milestones private.

Despite their desire for privacy, they occasionally share glimpses of their life together. Their joint appearance at the 2024 Golden Globes, where Olsen was nominated for her work in the series *Love & Death*, was a highlight, with Arnett proudly by her side. This balance of maintaining a private life while supporting each other's professional achievements is a key aspect of their enduring relationship.
