But in reality, some jobs can be grimmer than a CBB task.
Body positivity advocate and all-round bombshell Iskra Lawrence may be a jet-setting underwear model now, but her earlier gigs weren't exactly at Vogue level.
Speaking exclusively to the Daily Star Online, the curvaceous pin-up revealed that she refused to do some early modelling work because the auditions were so degrading.
Iskra said: "I mean, I've had to do terrible jobs, I can't believe I was put in some scenarios. I've had to be an umbrella girl at the races.
"The audition process for that is they have the whole team of drivers and engineers – all men – and they make a catwalk, and they make the girls walk down a catwalk and you get rated out of ten.
