"When you can accept that, you can just focus on being the best version of yourself," the cookbook author told TV Week. "My strategy for being in this very public space is just to focus on what I do well.

Her poignant message comes days after eliminated contestant Harry Foster went into bat for Melissa, squashing rumours she's "bias" and "rude".
"This could not be further from the truth. She's a queen and I love her," he told HuffPost Australia."She is energetic, passionate and really just vibrant. You can feel the energy. It's sort of like, she glows in a sense. It's really refreshing to see that."

The source claimed the 40-year-old food critic has been embroiled in multiple controversies behind the scenes, adding her "ego is out of control".
"Jock and Andy try not to engage with her when cameras aren’t rolling," the source added. "That isn’t hard as she spends most of her time in her dressing room working on her blog and social media, which frustrates producers who just want her to focus on the task she’s been paid to do."
