Two neighbors pull sharply ahead of the rest: Luke Hemmings at 0.97 and 5 Seconds of Summer at 0.97 — the bandmates whose audiences are, structurally, nearly identical to Ashton Irwin's own.

The shape here is two-peak. The first peak is the 5SOS cluster itself: Luke Hemmings (0.97), 5 Seconds of Summer (0.97), and Calum Hood (0.92) form a tight band of fellow Musicians and Bands, with Michael Clifford (0.91) close behind. These four share the same subcategory as Irwin and sit at the top of the neighbor set by a meaningful margin. The second peak is less obvious but real: Nash Grier (0.94) — a TV Personality — breaks into the top five ahead of several bandmates, signaling a distinct audience neighborhood that extends beyond the band's immediate orbit. Grey's Anatomy (0.92) reinforces this second cluster, representing the TV Shows subcategory and sitting above Shawn Mendes (0.91) and Daniel Howell (0.91, Comedians). Rounding out the top 10, Maroon 5 (0.91) and Liam Payne (0.90) return to the Musicians and Bands subcategory, while Zac Efron (0.89, Actors) marks a third subcategory present in the set. In total, six of the top 10 neighbors are Musicians and Bands, with TV Personalities, TV Shows, Comedians, and Actors each contributing one.

The two-peak structure reveals an audience anchored firmly in the 5SOS world but with a secondary pull toward youth-oriented TV and digital personalities — a shape that extends well past the band's own membership.
