How they've defined "Star" has always been somewhat loose. Jus picking some seasons at random:
Season 1
Trista Sutter (Reality TV star)
Evander Holyfield (Heavyweight boxer)
Rachel Hunter (Model)
Joey McIntyre (Singer)
John O'Hurley (Actor)
Kelly Monaco (Actress)
Season 9
Ashley Hamilton (Actor)
Macy Gray (Singer)
Kathy Ireland (Model)
Tom DeLay (Politican)
Debi Mazar (Actress)
Chuck Liddell (MMA Fighter)
Natalie Coughlin (Olympic swimmer)
Melissa Joan Hart (Actress)
Louie Vito (Snowboarder)
Michael Irvin (NFL player)
Mark Dacascos (Iron Chef Chairman)
Aaron Carter (Singer)
Joanna Krupa (Model)
Kelly Osbourne (Reality TV star)
Mya (Snger)
Donny Osmond (singer)
Season 18

AJ McLean (Singer)
Johnny Weir (Olympic figure skater)

Justina Machado (Actress)
Nelly (Rapper)
New Schulman (TV host)
Kaitlyn Bristowe (Reality TV star)
A lot of washed up and never-have-been actors, actresses, and singers. More and more reality stars. Athletes who are either past their playing days or capitalizing on Olympic success. A handful of models. The occasional politician.
