Oh to have Kylie Jenner's life. When she's not busy testing outnew makeup products for Kylie Cosmetics and posting pouty videosof herself eating elaborate snacks, she sometimes also likes to get a tattoo.

This week is no exception and following in the footsteps of Rihanna, Cheryl and, err, Judy Dench,she shared a sneaky little Snapchat vid of herself getting what looks like a bum tattoo.

While she is yet to share what the inking is of, Kylie did post a video showing a tattoo artist inking something onto her derriere as she laid on a couch.

This will be KJ's fifth tatt and with a teeny heart and grandma Mary Jo's name on her arm, she also already has a mini wave onher finger and the phonetic pronounciation of 'sanity' written on her hip.

The mystery tatt is yet to be referenced in any more snaps, but we do have a few theories of what exactly it could be of.

1. Every single one of her Lip Kits

Opting for a major bum tatt like Cheryl, we can totally see Kylie getting her pride and joy - aka her Lip Kits - inked down there. Granted it'd take up a lot of space, but seeing as they come in such pretty packaging, it'd totally be worth it.

2. Her dogs' names

If there's one thing Kylie loves more than lipstick, it's her dogs. And who wouldn't want Kermit, Ernie and Norman inked on their butt like a list of (admittedly geriatric sounding)former lovers?

3. A drawingof Tyga's gold teeth

Is there anything cooler than getting your boyf's golden grill inked on your arse? Yes, there probably is, but we can't imagine that would stop Kylie and the course of true love.

Any ideas of your own? Let us know with a tweet to @MTVUK.
