Did Khloe Kardashian just do a NAKED photobomb of her sister Kylie Jenner?

Kylie Jenner's got a lot on her plate, what with four older sisters to try and outshine, a faceful of lip fillers to deal with AND her own career to look after.

So we're not really sure why big sis Khloe Kardashian can't give her a break and let Kylie take the limelight for a bit.

Just look at this picture Ky's makeup artist Joyce Bonelli put on Instagram: a lovely candid snap of a business-but-friendly relationship, on-point filter, half-naked sister in the corner HOLD UP, WHAT?

Yep, Khlo decided to get her nips out and photobomb the 17-year-old, just because she could. Joyce captioned the snap: "@kyliejenner it's really not about us though□ @khloekardashian."

Looks like Khloe's super-proud of the results of her new fitness regime, but really: time and place, Khlo, time and place.
