Some beauty queens' misfortunes:

Beauty queens are required to adhere to strict personal and professional rules set by the pageant organisers in order to retain their titles and keep the scholarships and other awards for the year of their reign.

Property magnate and TV "reality" series star Donald Trump, who owns the Miss US and Miss Universe contests, will decide whether Tara Conner will keep the title after newspaper reports that the Miss US broke the rules on behaviour.

The following is a list of some fallen beauty pageant winners:

l 1973 - Marjorie Wallace, first American Miss World, lost her crown for dating too many men.

l 1984 - Vanessa Williams, first African-American Miss America, resigned after sexually explicit photographs of her appeared in Penthouse.

l1998 - Lejla Sehovic, Miss Croatia, was subjected to a second ballot in which she lost to the pageant's original runner-up. - Reuters
