The 19-year-old model has taken to Instagram Stories to rubbish recent criticism of their burgeoning relationship, and in particular, the 18-year age gap between herself and Scott, 37.

Amelia - who is the daughter of actor Harry Hamlin and actress Lisa Rinna - wrote: "ppl r extra weird and judgemental these days.. people can embrace themselves however they feel fit for them at that moment in time.

"people grow. people learn to love themselves more and more (sic)"

Amelia recently started dating Scott following his split from Sofia Richie earlier this year.

However, their romance - and the age gap, in particular - has attracted some criticism.

A source recently insisted that neither Amelia nor Scott are not "looking for anything serious" at the moment.

The reality star - who has kids Mason, 11, Penelope, eight, and Reign, six, with Kourtney Kardashian - loves being with Amelia, but their romance is said to be fairly casual for the time being.

The source said: "He is enjoying her company. She doesn't spend time with the kids at all and Scott only sees her on his days off from his kids."

Earlier this month, meanwhile, Sofia suggested she'd outgrown her relationship with Scott.

The 22-year-old model wrote a cryptic post about love on her Instagram Stories.

Sofia said: "Sometimes we outgrow people we used to know and become different people. When this growth happens, some take our changes personally. Not because they have anything against us but because they do not recognize the person that we are now (sic)"

Sofia also suggested that she's changed significantly over recent years.

She wrote: "You’re not responsible for people’s assumptions about you. You’re also not obliged to remain the person people remember you to be."
