Miranda Kerr doubted career's longevity

Supermodel Miranda Kerr was doubtful whether her career will last long enough, but the 30-year-old is glad that even after so many years of being in the industry, she can seek new challenges.

Kerr, who had first brush with modelling when she was 14 and a friend secretly enrolled her in a modelling competition, spoke of her success story in the May issue of Britain's GQ magazine, reports femalefirst.co.uk.

"It's funny, some people have recently said, 'Oh your career is really starting to take off', which is weird. I think they forget I've been doing this since I was 14. Maybe it just seems that way to the fashion crowd as for a long time I was doing more commercial jobs. I just feel lucky. I never thought it would even last this long," she said.

Kerr now reportedly makes $8 million annually, according to Forbes magazine.

She was the first Australian model to be named a Victoria's Secret 'Angel'. She ended her contract with Victoria Beckham's underwear brand last year, but she has no regrets.

"I treasured my time with (Victoria's Secret). I wanted a new challenge, a new scene," said the model, who has her own skincare range, and who is also the face of Swarovski jewellery and H&M's spring/summer 2014 campaign.

She is also a full-time mother to her three-year-old son Flynn with her estranged husband Orlando Bloom.
