Twiggy (born Lesley Hornby) is an English supermodel, actress, and singer, now also known by her married name of Twiggy Lawson. A 1960s model known for her large eyes, long eyelashes, and thin build, she is regarded as one of the most famous models of all time.

Twiggy went on to star in movies, and appeared as a judge on the reality show America's Next Top Model. She now models for Marks and Spencer to promote their recent rebranding, and appears in seasonal TV adverts with others such as Myleene Klass, as well as other forms of media for the campaigns.

In 1966, Nigel Davies noticed the young Lesley Hornby and offered her a modelling contract. She was only 16 and weighed 6½ stone (41 kg, 90 lbs).[4] Davies advised her to go by her childhood nickname, Twiggy, and renamed himself Justin de Villeneuve.

After sweeping England as "The Face of '66" when her modelling pictures, taken by Barry Lategan, were made public, Twiggy arrived in New York in March 1967. It was believed that the Twiggy craze would die down within a month; however, she became an icon and a supermodel.

Known for the high fashion mod look created by Mary Quant, Twiggy changed the world of fashion with her short-haired androgynous look. She was also famous for drawing long, fake eyelashes under her bottom lashes.

Twiggy was regarded as one of the faces of 1960s Swinging London, along with other models, such as Jean Shrimpton and Celia Hammond. On 16 June 1967, Capitol Records released Twiggy's first single for the label "When I Think Of You" with "Over And Over" on the B-side.

In early 1968, she toured Japan and filmed advertisements for Toyota Motors and Choco Flakes breakfast cereal. In 1969 she did advertising work in the United States for Diet Pepsi Cola.
