The Extra Camp presenter has been trolled by fat-shamers since putting back on the three stone she lost in 2016.
But the Gogglebox star, 27, has no plans to slim down before flying to Australia ahead of her presenting job this autumn.
Her friend told the Daily Star Sunday: “Scarlett is over the fat-shamers and people who say nasty things for attention.
“She’s saying she is now just going to ‘own her curves’.
“She was a size 18 when she first found fame and that’s when the public got to know and love her.
“Scarlett doesn’t need to be skinny to be famous – it’s her personality everyone loves.
“Finally, she’s getting that. She’s packing some great dresses and is going to just totally own being big and beautiful.”
