More than 5,000 people were kicked off BeautifulPeople.com for losing their looks over the holiday season.
The site, which has a strict ban on ''ugly people'', said it had thrown out more than 5,000 members from around the world who had put on weight.
Most of the ''former beauties'' were expelled from the US, UK and Canada.
According to BeautifulPeople.com, ''vigilant members'' called for drastic action after users posted photos of themselves celebrating Christmas and the New Year - revealing they had ''let themselves go''.
Robert Hintze, founder of BeautifulPeople.com, said: ''As a business, we mourn the loss of any member, but the fact remains that our members demand the high standard of beauty be upheld.
''Letting fatties roam the site is a direct threat to our business model and the very concept for which BeautifulPeople.com was founded.''
