Katy Perry's top 10 neighbors form a dense, undifferentiated cluster — scores run from 0.98 down to 0.95 with no single dominant pull and no sharp drop-off between positions. That compression is the structural finding: the audience shape here is broadly shared across a wide swath of mid-2000s to mid-2010s pop culture.
Similarity here measures how closely two entities' audiences resemble each other in composition. Justin Bieber (0.98) and Christina Aguilera (0.98) sit at the top, followed closely by Kris Jenner (0.98) and Britney Spears (0.97). The subcategory breakdown across the top 10 is telling: six of the ten are fellow Musicians and Bands — Bieber, Aguilera, Spears, Demi Lovato (0.97), Iggy Azalea (0.96), and Ashley Tisdale (0.96, though Tisdale is classified as an Actor). Three neighbors are Reality TV Stars — Kris Jenner, Kourtney Kardashian (0.96), and Khloé Kardashian (0.95) — and one is a TV Channel: MTV (0.95). The Kardashian-Jenner cluster appearing this high alongside musicians is the cross-kind note worth flagging; reality TV stars occupy three of the top ten slots, matching the weight of the musician neighbors.
The flat shape means no single neighbor defines this audience — instead, the same crowd appears to follow pop musicians, reality TV personalities, and the channel that historically bridged both.
