'Don't tell me she dyed her hair' Jessica Simpson criticised over latest snap of daughter Maxwell

Singer Jessica Simpson received serious backlash from fans after posting an adorable snap of her family dressed up for Halloween.

The mum-of-two captioned it with: 'Willie, Waylon, Belle and Cowboy Ace #Halloween2017'

But fter posting the family picture, many of Jessica's 4million followers noticed that her daughter Maxwell looked very different.

Jessica's daughter, Max, typically has very blond hair, like her mum, but it's obvious she's rocking a much darker 'do as Belle for Halloween - and people were very quick to ask if Jessica had dyed her daughter's hair.

'Did you colour Maxi's hair?' asked one follower.

'Is Maxwell's hair dyed?' questioned another/ 'I hope not her blonde hair was so beautiful!!! Hopefully just temp wash out color.'

This fan used crying emojis to highlight her opinion: 'Did you dye her beautiful blonde hair @jessicasimpson 😭😭😭 or spray color.'

However, there were a few fans who came to the star's defence: 'I dyed my daughter daughters hair for Halloween blue and purple what's the issue it's hair it grows. Yes it was wash out hair dye buy. Honestly it's her kids who cares.'

'Max looks so different with brown hair. She is just absolutely gorgeous.Love it!' another fan, followed by one who agreed: 'It's hair, it's not like she got her a damn tattoo.'
