It seems Hollywood is taking it farther than ever to get that hourglass shape, as more and more celebs are strapping on tiny corsets to join the waist training trend.

It might look painful, we might not know where the organs go, and it definitely might make it harder to breathe, but that doesn't stop these stars from giving waist training a go (and often being very vocal about it online).

Here are 8 celebs who waist train.
