Kate Upton thinks modelling is a ''fun journey''.

The blonde beauty has already achieved her life goal aged 20 after appearing on the cover of Sports Illustrated magazine, and is now looking forward to the exciting opportunities the fashion industry can bring.

She said: ''My dream was always to be on the cover of Sports Illustrated. I grew up with that magazine, it was always at home. But now that I've done that, I'm really enjoying finding out more about the fashion industry. I'm not sure what my next goal is, but it's a fun journey.''

The curvy star - who is a US size eight - was discovered at a horse show when she was 12 years old and took a chance on a world she knew little about, moving to Miami aged 15 to begin her career.

She told Britain's Vogue magazine: ''At that point I didn't know anything about modeling and so later I researched it - I looked online at some of the measurements. I was the right height, so I thought I'd give it a go.''

The sexy star struggles to find clothes by designers that fit her womanly figure, especially since her chest is much bigger than the average stick-thin model's.

Kate laughed: ''It's complicated for a model with boobs!... I need something without build-in pads. I don't want to make them look bigger!''
