Millie Mackintosh struggled with Celebrity MasterChef and the pressures that came with it.
The former 'Made In Chelsea' star admitted she was a "nervous wreck" while filming for the upcoming new series of cooking show, although looking back she is "really proud" of herself.
She said: "It's been amazing. Watching it back I felt really proud and was fist pumping and jumping up and down!
"But I was a bit of a nervous wreck at the time. I was quite difficult to be around because the nerves made me quite uptight. I wasn't sleeping much."
Due to the stress of the celebrity contest, Millie found herself battling fatigue as she tried to keep on top of everything - although she eventually "burst into tears" when it almost became too much.
She added: "Catering for loads of people was really stressful because of the pressure to get everything done. At the end I burst into tears because I was so exhausted."
And while the star didn't put on a lot of weight, she did notice her "eating habits got worse".
She admitted: "I tried to fit in the gym as much as I could, but filming made it difficult. I didn't find that I put on weight but my eating habits got worse.
"It was hard not to snack on the crisps and sandwiches available, so I started making healthy food the night before."
