Cara Delevingne turns down 70 per cent of the work she's offered.
The model-of-the-moment is signed to Storm Model Management and co-founder Sarah Doukas has discussed what working with her is like.
Delevingne walked several shows during the recent Fashion Week season, has created a capsule collection for Mulberry and appears in many campaigns.
However, Doukas is determined not to let her become over saturated and explained many of the offers made to her are dismissed.
"We spend our lives saying no," she told students at Conde Nast College.
Storm is also the work home of Kate Moss, who was discovered by Doukas.
The two models recently caused excitement when it was confirmed they had teamed up for a Burberry campaign. While both are hugely successful, Doukas explained there are plenty of differences between them.
"For Cara it just comes naturally to use social media and it's just part of the way she lives," she said. "I mean the other day she took a selfie on the catwalk. Nobody else from another generation, perhaps Kate's, would even consider doing that."
The model booker also dished out some advice to those hoping to make it in the industry. She insists confidence is the most important thing, so if someone thinks they have what it takes they need to really push for it.
"Just go for it and walk through the door!" she said. "A good agency will be able to tell from even a Facebook profile or a phone photo if you have the potential - expensive portfolios are never necessary."
