Aged 15 and while still a student at the
Italia Conti Academy, Campbell was spotted by Beth Boldt, former head of Synchro models agency, while window-shopping in
Covent Garden. Campbell soon opted to become a fulltime model, signing with
Elite Model Management. Of her looks, she has said: "My features are completely ethnic, and I'm proud of them."
Although Campbell started her career as a catwalk model, she was quickly hired for various high-profile advertising campaigns, including
Lee Jeans and
Olympus Corporation, which introduced her to the
American market. Campbell also completed campaigns for
Ralph Lauren and François Nars. In April 1986, she appeared on the cover of
Elle, replacing a model who had canceled out of the appearance.
In August 1988, she appeared on the cover of
Vogue Paris as that publication's first
Black cover girl. In addition to
Vogue Paris, Campbell also became the first
Black model to appear on the cover of
Time magazine,
Vogue UK and
Vogue Nippon. She has also posed nude for
Playboy and appeared in
Madonna's 1992 book
Sex, in a set of photos with Madonna and rapper
Big Daddy Kane. In total, Campbell has appeared on more than 500 magazine covers.
She famously starred in
George Michael's music video
Freedom! '90, where she
lip-synched to his song along with fellow supermodels
Linda Evangelista, Christy Turlington, Cindy Crawford and
Tatjana Patitz. In 1992, Campbell appeared in
Madonna's music video for
Erotica, which featured filmed footage from photoshoots for the book
Sex. In addition to the previously mentioned music videos, Campbell has appeared in videos for artists such as
Michael Jackson, Nelly, Jagged Edge, Jay-Z, P.Diddy, The Notorious B.I.G, Macy Gray, Prince and
Usher.
The highpoint of Campbell's career was in the early 1990s, when she was part of the two major supermodel powerhouses: the Big Six, alongside
Cindy Crawford, Claudia Schiffer, Christy Turlington, Linda Evangelista and
Kate Moss, and the Trinity, alongside
Turlington and
Evangelista.
