María Guadalupe "Lupita" Jones Garay (born September 6, 1968 in Mexicali, Baja California, Mexico) became the first Mexican woman to win the title of Miss Universe in 1991.

Representing the state of Baja California, Jones won the title of Señorita México (Miss Mexico) in September, 1990.

A few months later, on May 17, 1991 in Las Vegas, Nevada, she and 72 contestants competed for the title of Miss Universe 1991.

Lupita became the clear favorite of the judges, entering the semifinals of the pageant in first place, the only delegate with an average score above 9. During the final telecast, Jones breezed through the competition, winning everything: swimsuit, interview and evening gown. As the indisputable leader, she dominated with her articulate answers the next two rounds of competition (the Top 6 judges' questions and the Top 3 final question), winning it all, the crown, the prizes and the prestigious title for her country.

Jones had studied business administration before Miss Universe and also did post-graduate studies in industrial administration at the Centro de Enseñanza Técnica y Superior in her native city of Mexicali, Baja California.

Osmel Ricardo Sousa Mancilla (born 26 September 1946) is a Cuban-Venezuelan beauty pageant gurú and the president of the Miss Venezuela Organization. Formerly an advertising draftsman, Osmel Sousa joined the Venezuelan Committee of Beauty in 1969. Sousa continued working with that committee when, in 1970, Ignacio Font Coll reconstituted it as the OPPA Advertising Agency, which in turn was the predecessor of the actual Miss Venezuela Organization.

In the 1970s, Osmel Sousa undertook advising selected contestants, many of whom went on to win the Miss Venezuela crown, at the same time he started designing nightgowns for most of the contestants.

In October 1981 Ignacio Font Coll died and Osmel Sousa became the president of the Miss Venezuela Organization. During his 25 year career he has been considered to be the driving force behind the large number of Miss Venezuelas who go on to become Miss World, Miss Universe, Miss International and Miss Earth. He has been called a Pygmalion, an artist who turns out talented and beautiful young women. To date, Venezuela has six Miss Universe titleholders, six Miss World winners, six Miss International crowns, and one win in Miss Earth, becoming the most successful pageant powerhouse in history.
