We often wonder how Kim Kardashian's boobs always look so perfect when she's on the red carpet. 

Because, let's be real – in the real world if you have boobs that big, they do not stay up or even stay put for that matter.

But, Kimmy has let us in on a little secret that she uses for big events, and while her chest looks great, it also looks quite sore.

The reality star shared a photo on her website, showing nothing but straps of tape on her boobs. 

Along with the photo, she wrote: "I definitely had to share my tape secret with you guys!! It's my secret trick to have perfect cleavage in photos.

"You tape them up so they are super lifted. It takes a little work but trust me it's all worth it LOL," she added.

She also said that the best tape to use is gaffer tape. Eek!

"It sticks the best! Just brace yourself for when it's time to take it off LOL."

We don't know about you, but we think we'll stick to push-up bras. This just looks way too painful.
