Kim shared the picture of a happy looking North with the caption 'SMILE.'
Fans soon took to twitter with their suspicions that Kim had opted to tidy up her young daughter's supposed uni-brow.
One twitter user wrote: 'Kim K definitely waxed her baby's unibrow.'
Some even suspected Kim of filling in her daughter's brows with make up.
Katie Keegan then tweeted : 'I swear the instagram pic Kim Kardashian just put up looks like her baby's eyebrows are filled in and waxed.'
Lauren Irey tweeted: 'That awkward moment when Kim Kardashian's baby has a better eyebrow game than you.'
A spokesperson for Kim denied the claims, branding them as 'completely false.'
Kim is not the first celebrity to be caught up in such a controversy. Teen Mom star Farrah Abraham has admitted to tidying up her daughter Sophia's eyebrows whilst she slept.
Katie Price and Peter Andre famously fell out with one another after Katie straightened their daughter Princess' hair and allowed her to wear make-up.
Do you think it's right to groom a baby's eyebrows?
