the name of physicist Albert Einstein

Little girls, however, were referred to as 'social butterflies'

Twitter users called out Gap Kids for the ad,

An advert for Gap Kids' latest campaign sent out to UK customers has been labelled as 'sexist' on social media - with people also pointing to a spelling mistake in the images.

The clothing company has come under fire for the advert featuring children's clothes that refers to boys as 'scholars' and girls as 'social butterflies'.

Twitter user Sabrina Golonka was the first to tweet the image after she received Gap's email - provoking a flurry of tweets.

Clothing brand Gap appears to have ruffled a few feathers with it's latest advertising campaign, above, branded sexist by Twitter users

One eagle-eyed person also noted that the name of Albert Einstein, the German-born theoretical physicist, is spelled incorrectly on the little boy's T-shirt as 'Einstien'.

The other advert shows a little girl wearing silver cat ears, navy trousers and a yellow jumper with a pink 'G' on it, over a blue shirt.

It says: 'The Social Butterfly. Chambray shirts + logo sweaters are the talk of the playground [sic].'

The little boy's ad shows a grinning child wearing a T-shirt with Einstein's face on it, and reads: 'The Little Scholar. Your future starts here. Shirts + graphic tees = genius idea. [sic]'

The advert calls a little girl The Social Butterly - while wearing silver cat's ears, navy trousers and a yellow jumper with a pink 'G' on it, over a blue shirt

However, the little boy is referred to as The Little Scholar - wearing a T-shirt with Albert Einstein's name misspelled

Comments claiming the advert is sexist have come rolling in.

Psychologists Andrew and Sabrina were among the first to notice the difference in the style of advertising, which appeared in a promotional email sent around by Gap UK.

'Just...no,' the pair tweeted from their joint account @PsychScientists.

Jane Etheridge, @janesetheridge, was highly effected by the advert, and wrote: '@malorieblackman @LetToysBeToys @UKGap that actually made me feel ill. Unbelievable.'

Penelope, @gecko_woman, was exasperated, and said: '@LetToysBeToys for goodness sake @UKGap how can you seriously think that is OK?'

The account which had been tagged, Let Toys Be Toys, a parent-led campaign attempting to reduce gender specific advertising for toys, tweeted: 'For anyone who thinks that sexist marketing to children isn't a problem...Really @UKGap?'

The group grew out of a thread on parenting site Mumsnet which brought together parents frustrated by gender-based promotion aimed at children.

In a highly ironic twist it also appears that despite the assertion that boys going back to school should be scholarly, a spelling error appeared in the advert.

Albert Einstein's name is spelled 'Einstien' on the little boy's t-shirt.

The clothing giant has been in hot water previously for a children's clothing advert branded 'passively' racist.
