Victoria Beckham has reportedly been ''disgusted'' by people fat-shaming her daughter Harper.

The 43-year-old fashion designer and her husband David, 42, have both been left feeling shocked and appalled by the cruel comments of social media users in response to a picture of six-year-old Harper enjoying a day out at the beach with her older brothers, Brooklyn, 18, Romeo, 15, and Cruz, 12.

An insider told the Daily Star newspaper: ''Victoria was shocked and disgusted by the comments over her little girl.

''It really upset her and she would hate for Harper to ever read comments like those and become obsessed about her body image.

''David was fuming and wanted to post something about it on social media but was told not to as it may encourage the trolls.''

Victoria has reportedly told people around her that while she isn't fussed about the criticism she receives, the former Spice Girl will not tolerate cruel comments directed at her children.

She was, for instance, angered by the negative reaction to Brooklyn's launch of his photography book 'What I See', which was blasted by critics.

The insider explained: ''The recent comments over Harper just prove to her and David how vicious and vile people can be about their family.''

Meanwhile, David previously revealed he intends to adopt a stricter approach to Harper's love life than he's done with his boys.

Speaking in 2016, the retried soccer star explained: ''Obviously Brooklyn is definitely at that age.

''We're strong parents, and strict parents, but we're like most parents. We love our kids and we want the best for them, so we'll see.''

But asked if things will be different with Harper, David laughed and then added: ''Oh yeah. That'll definitely be different!''
