I’m guessing based on Louisiana’s (Britney Spears), they used search traffic and there’s a bias toward people who have scandals that drive periodic spikes in search traffic. There’s bigger celebrities from Louisiana than her but they aren’t really tabloid fodder.

Peyton Manning is probably more famous in the U.S. He’s constantly doing commercials and won multiple Super Bowls. Reese Witherspoon was the highest paid Hollywood actress in 2023. She’s gotta be more famous globally or Hollywood studios wouldn’t be giving her bags of money. I’m sure they both have way higher Q-scores than Britney Spears but are pretty much scandal-free.
