The former MasterChef Australia favourite made another untimely exit from Channel 9's Celebrity Apprentice - after failing to reign in Baywatch star David `The Hoff' Hasselhoff in an art challenge.The friendly foodie conceded her "niceness'' may have worked against her on a TV program punctuated by powerful personalities and rampaging egos.TV boss Mark Bouris acknowledged her "gentle soul'' during boardroom discussion's following this season's art project episode, which saw Grasby lead Team Fortune to a loss against the Ian `Dicko' Dickson-led Team Platinum.But the meek-and-mild creator of Marion's Kitchen food range proved too sweet for the celebrity series."Before I went on the show I thought to myself `you know what, I'm going to have to really toughen up otherwise these people are going to be mean to me,'' Grasby told www.thetelegraph.com.au."But at the end of the day, I just can't be someone that I'm not.''Getting to know the personalities on board this season proved a mystery box, with Grasby warming to Charlotte Dawson, Ben Dark and Dicko."They were the big surprises for me. I found them really supportive and nice and lovely, even if they don't come across like that on the show.''Featuring in promos describing Dawson as a "bitch,'' Grasby said: "I think she's must nicer than she lets on. While she pretends to be mean, she's really not that mean at all.''This year's Deni Hines-style villain, Tania Zaetta had the ability to "rub people up the wrong way,'' Grasby revealed."I didn't know much about Tania before (the show). It surprised me how much people can rub people up the wrong way. Not that I think she was doing it intentionally. She's not a malicious person.''Ever-the-sofie, she added: "I think it's a bit sad that Tania's the villain. I hope by the end of the series people like her a lot more. She's just someone who talks a lot really...(laughs).''Grasby joked her early departure was "true to form'' given the national headlines she made after her shock elimination from the 2010 series of MasterChef."I think everyone thinks they're going to win when they sign on (Celebrity). I of course have already lost a reality TV show, so I'm just being true to form. Winning didn't really work out for me.''The Adelaide-based food writer and home-meal range creator is in Singapore attending a trade show and researching new products for her brand.But it may not be the last we see of Grasby on Nine's celebrity series. Stay tuned.
