I think this is her 25th or 26th collapse in the last 2 months. Jon Murray, the series creator said that Nicole felt woozy a couple of times and so had to sit down. However, filming continued after a five or ten minute wait. Female First states that Nicole collapsed and couldn't film for the rest of the day. I guess since they are fat camp counselors, Nicole is just dieting right along with the children. She must be all of 5-10 pounds underweight so by all means she should be dieting. Also she is showing those kids that even if they lose hundreds of pounds, Nicole thinks it is still a good idea to lose even more. Of course all of this could just have been heat related, or the stress of a wedding or having Paris Hilton as your friend.
