Die-hard Keeping Up With The Kardashians fans will know all too well that Kim has never been the biggest fan of tattoos. Unlike the rest of her famous family members who have experimented with various super-personal and largely teeny-tiny designs, the Skims founder has remained proudly ink-free – or so we thought...

Despite once famously joking that her getting a tattoo would be the equivalent of putting "a bumper sticker on a Bentley", Kim Kardashian revealed during the most recent episode of The Kardashians that she does in fact have a secret tat of her own – and it's in one *seriously* unexpected spot.

"You guys, something you don't know about me... Me and all my friends got matching tattoos and everyone got them on their hands and I was like, 'There's not a shot I will get a tattoo,'" she said in last night's episode.

So, where did she get it? On the inside of her lower lip, of course! During the episode, Kim pulled down her lip to reveal her tiny black infinity symbol tattoo for the camera. You can't get much more discreet than that!

The episode also showed some never-before-seen BTS footage of Kim getting said tattoo with friends following her Saturday Night Live hosting debut. "This is how you celebrate SNL, with a little tattoo at 4.30 in the morning," she said, revealing the meaning behind the ink.

"No one knows, no one sees it, I forget," she continued. "But every once in a while, I'll be flossing my teeth and I'll see black and I'll go, 'What's this black thing?'"

Say what you will about Kim, but she's certainly full of surprises.
