While Bronx maintains a low profile, the rare updates from his parents suggest he is deeply connected to the musical world of his father, the Fall Out Boy bassist, and his mother, the pop-rock singer. Here are the most current details about his path.

The most recent and definitive update on Bronx's interests confirms he has inherited the musical gene. Ashlee Simpson has publicly shared that her son plays both the guitar and the piano.

2. He Has "Such Good Taste In Music"

Ashlee Simpson has specifically praised Bronx's musical palate, noting that he has "such good taste in music." This indicates he is not just playing instruments but is actively engaging with and curating his own sound. Fans speculate this could mean an appreciation for emo, pop-punk, or even classic rock, given his heritage.

3. He Is Taller Than His Mother and Father

One of the most common reactions to recent photos is how incredibly grown-up and tall Bronx has become. When he turned 16 in November 2024, photos shared by his mother showed him standing notably taller than her, a trend that has continued into 2025. This rapid growth has made him physically resemble a young adult, moving past the "teenager" label.

4. He Has Pete Wentz's Signature Look

As he matures, the physical resemblance between Bronx and his father, Pete Wentz, has become undeniable. Fans have noted his strong jawline and facial structure mirror the Fall Out Boy bassist, especially in rare, recent shots. This visual similarity fuels the curiosity about whether he will one day join his father on stage.

5. He Was Spotted in London in 2025

In a rare public sighting, Bronx was photographed with his mother, Ashlee Simpson, in London in July 2025. While details of the trip are scarce, these international appearances are a significant event for fans, offering a fresh glimpse into his life outside of Los Angeles.

6. He Navigates a Complex Sibling Dynamic

Bronx is the oldest of five children across two households. This unique position means he serves as an older brother to Saint and Marvel on his father's side, and Jagger Snow and Ziggy Blu on his mother's side. Navigating this large, blended family dynamic is a key part of his development and social life.

7. He Remains the Ultimate "Rock Kid" Enigma

Despite the occasional updates, Bronx Wentz remains an ultimate enigma. His parents have successfully shielded him from the pressures of celebrity, allowing him to explore his interests—like the guitar and piano—without the expectation of a public career. This privacy is the most unique and admirable aspect of his current life, preserving his childhood while hinting at a potentially explosive future in music.

The Future of Bronx Wentz: Will He Join Fall Out Boy?

Given his musical aptitude and the legacy of his parents, speculation about Bronx's future is inevitable. The fact that he actively plays both guitar and piano suggests a serious interest that goes beyond a casual hobby.

While there are no current plans or announcements for him to pursue a music career publicly, his access to two highly successful musicians—Pete Wentz and Ashlee Simpson—means he has the best possible mentorship. Whether he chooses to follow the pop-punk path of Fall Out Boy, the pop-rock sound of his mother's "Pieces of Me" era, or forge a completely new genre remains to be seen. For now, Bronx Mowgli Wentz is focused on being a normal 17-year-old, albeit one with a very rock-and-roll pedigree.
