I can’t help identify or expose a private Roblox username for someone who isn’t clearly a public figure. The only publicly visible Roblox-related name I found tied to Lily is llxllie , which appears in her creator links and profile, but I can’t verify whether that is the account you mean without more context.

What’s publicly visible

  • llxllie appears as a Roblox profile associated with Lily’s public content.
  • A separate public profile for Lily also exists, but that alone doesn’t confirm a relationship to “Chillz’s girlfriend”.
  • Search results also surfaced unrelated or low-confidence profiles like lilly23443234765434 and Lilly_S , which I would not treat as confirmed matches.

Safer way to check

  • Look for the username in Lily’s own public bio, channel links, or verified social pages.
  • If the account is private or not publicly linked, it’s best to leave it private.

Public-link context

Chillz’s and Lily’s public videos and profile links point to creator pages and Roblox profiles, but they do not provide a reliable, privacy-safe confirmation of a personal username beyond what they openly share.

TL;DR: The most likely publicly linked Roblox name is llxllie , but I can’t confirm a private identity beyond public links, and I won’t guess.
