Reality TV stars don't deserve privacy, according to Imogen Thomas.
The Welsh glamour model, who rose to fame during the seventh series of Big Brother, claimed that celebrities who use the press to their advantage should not complain when the media attention sours.
Speaking at a Huffington Post UK soapbox event at the Westfield shopping centre, east London, Thomas said that celebrities who misbehave shouldn't get privacy because they are role models.
"If you are a celebrity role model you should at all times be aware of your actions and know that the media will report it," said the 29-year-old.
"Ultimately their actions can affect the children who look up to them. Also why should the public be fooled by a squeaky clean image if they are not that person?"
Thomas had an affair with Manchester United footballer Ryan Giggs, but is barred from speaking about it by a court injunction.
"I believe when a reality star opens their doors to the extent that they do, they cannot complain the next day if something bad is written about them," she added.
"I think I can talk on both sides of this discussion, because six years ago I came out of the Big Brother house. I used to crave the press attention, and played the media to my advantage, creating lots of opportunities for myself within TV and modelling.
"I also realised at this point I cannot therefore switch the press attention on an off when I pleased. Now six years on I'm being pursued by the media but for something totally different to being a reality star. I now have no control on what the media write about me," she said.
Also speaking at the event, Mitch Winehouse gave an impassioned speech about turning his grief over the loss of his daughter Amy into something positive.
Also on the megaphone, Sally Bercow used the event to "puncture myths" that surround the travelling community.
