Nadia Forde has revealed that the competition is already heating up in TV3's Celebrity MasterChef kitchen, with some contestants in particular being very competitive.

"It's all these [people saying] 'I don't cook' but really, they do - I was the only honest one that said I don't cook, and I really didn't cook!" Forde told RTÉ Entertainment at the launch of TV3's autumn schedule on Wednesday.

The model will compete with the likes of RTÉ weather forecaster Evelyn Cusack, former Miss Ireland Holly Carpenter and singer Niamh Kavanagh for the title, but she added that even if she doesn't win, she'll be glad to leave the show with some new cookery skills.

"I feel like no matter what happens I'm leaving the show so much more educated about food than I was," Forde said. "And I mean, I was at rock bottom, so anything is an improvement from where I was."

Forde was originally apprehensive about signing on to take part because she "can't cook", but getting to work at home in Ireland was a big bonus.

"It's amazing. I love Ireland and there is no place like home," she said.
