Robbie Arnett isn’t a household name on his own, but search interest in him has spiked hard this week. People want to know who he is, what he does for work, and — most of all — what’s true about the baby news currently making headlines. Here’s a fact-checked look at his life, career, and the update everyone’s actually searching for.
Background: Who Is Robbie Arnett?
Robbie Arnett is an American musician and one of the founding members of the Los Angeles indie band Milo Greene. He sings and plays multiple instruments in the group, which he helped start with college friends around 2009, with the band becoming fully active by 2011. Their self-titled debut album came out in 2012 and reached number one on Billboard’s Heatseekers Albums chart.
Most people don’t search his name because of his music, though. They search it because he’s married to Elizabeth Olsen, the actress known for playing Wanda Maximoff (Scarlet Witch) in the Marvel Cinematic Universe and for her Emmy-nominated role in WandaVision. Olsen is also the younger sister of Mary-Kate and Ashley Olsen. Arnett and Olsen have kept their relationship notably private since they started dating in 2017, which only fuels more curiosity whenever new details surface.
Latest Update
As of August 17, 2026, here is what’s currently known: Elizabeth Olsen and Robbie Arnett have welcomed their first child together. The couple was photographed taking a walk in Los Angeles on Saturday, August 15, 2026, with Olsen carrying an infant in a baby carrier. Multiple outlets, including People and Page Six, independently reported the sighting, and it followed earlier photos from June 2026 that showed Olsen with a visible pregnancy.
Key Dates Confirmed So Far:
| Date | What Happened |
|---|---|
| June 2026 | Olsen photographed in Los Angeles showing a baby bump, confirming the pregnancy |
| August 7, 2026 | Olsen seen in Southern California, no baby bump visible |
| August 15, 2026 | Olsen and Arnett spotted walking with a newborn in a baby carrier in Los Angeles |
| August 16-17, 2026 | Story picked up widely by entertainment outlets as the couple’s first public outing as parents |
Still Unconfirmed: The baby’s exact birth date, sex, and name have not been shared by Olsen or Arnett. Neither has made an official announcement or statement, so any specific details you see beyond what’s listed above should be treated as unverified rumor rather than confirmed fact.
Full Profile
Family and Early Life
Public information about Arnett’s childhood and parents is limited, since he keeps his personal life mostly out of the press. Fan-run biography sites list his birth date as March 3, 1992, but this has not been confirmed by any major outlet, so it should be treated as reported rather than verified.
Career Path
Arnett co-founded Milo Greene with college friends, and the band signed with Chop Shop/Atlantic Records. He handles lead and backing vocals along with guitar and other instruments. The band released three studio albums — Milo Greene (2012), Control (2015), and Adult Contemporary (2018) — and has continued performing since. Outside music, Arnett has small on-screen and soundtrack credits, including work connected to the 2019 film Jexi, and he co-wrote the children’s book series Hattie Harmony with Olsen, which focuses on helping kids manage worry and big feelings.
Age
Based on the commonly reported 1992 birth year, Arnett is 34 years old as of 2026. This age lines up with how recent entertainment coverage refers to him, though his exact birthday remains unconfirmed by a primary source.
Religion
Some fan biography pages describe Arnett as having a Christian upbringing. Neither he nor Olsen has discussed his religious beliefs publicly, so this detail is unconfirmed.
Spouse/Partner
Arnett is married to actress Elizabeth Olsen. The two met while both were traveling in Mexico in early 2017 and went public with their relationship that same year. They got engaged in July 2019 after roughly three years of dating. Olsen has said in interviews that the couple eloped and held a separate wedding celebration before the COVID-19 pandemic hit in 2020, meaning the marriage happened sometime before that point. Some entertainment databases list a 2021 marriage date instead, so the exact wedding date is not something the couple has confirmed publicly, and different outlets report it differently.
Net Worth
Robbie Arnett’s net worth is not something he or his representatives have disclosed. Some celebrity-finance sites estimate it somewhere between $2 million and $5 million, based on album sales, touring, and songwriting income, but this figure is an outside estimate, not a confirmed number.
Parents
No verified information about Arnett’s parents’ names or occupations is publicly available. This should be treated as unconfirmed rather than left out entirely, since it’s a common thing readers search for.
Height
Reported figures for Arnett’s height vary between roughly 5 feet 10 inches and 5 feet 11 inches, depending on the source. Neither number comes from a verified, first-party statement, so treat this as approximate.
Education
According to interviews with his Milo Greene bandmates, Arnett attended the University of California, Irvine, where he met the college friends who would later become his bandmates. Some fan sites also mention an earlier high school, but that detail hasn’t been independently confirmed.
Hometown/State of Origin
Multiple biography sites list Los Angeles, California, as Arnett’s birthplace, and he has lived and worked in the Los Angeles area throughout his music career. This detail carries a reasonable amount of confidence but is not confirmed by a primary source like a verified interview.
Official Social Media
Arnett’s Instagram account is @robbiearnett, which has been referenced by entertainment outlets covering his relationship with Olsen since 2017. His band’s official channels can be found under Milo Greene.

Wrap-Up
Robbie Arnett’s public profile has always been shaped by two things: his ongoing work with Milo Greene and his low-key marriage to one of Hollywood’s more private stars. That privacy is exactly why search interest spikes every time new photos surface — people are filling in gaps that the couple has chosen not to fill in themselves.
The confirmed news this week is straightforward: Olsen and Arnett have welcomed their first child, and they were seen together in public for the first time as parents on August 15, 2026. Everything beyond that — the baby’s name, birth date, and sex — remains unannounced, and readers should treat any specific claims about those details as unconfirmed until the couple says otherwise.
As with most of Arnett’s life outside music, expect the couple to keep new details limited. If and when Olsen or Arnett share more, credible outlets like People, the Associated Press, or Olsen’s own social channels will likely be the first accurate source, rather than fan pages or secondhand claims.
