Victoria Beckham feels ''sick'' ahead of her fashion shows.

The singer-turned-fashion designer always feels overwhelmed when showing her collections for the first time and was delighted by the response her spring/summer 2013 Victoria Beckham runway show received at New York fashion week.

She told Grazia magazine: ''Before the collections go out, I feel sick to my stomach.

''I was completely overwhelmed and ecstatically happy when I walked on to the catwalk at the end.''

Despite the overwhelmingly positive response to her Victoria Beckham and Victoria by Victoria Beckham collections, Victoria is not getting carried away with her success, though she is delighted with her achievements.

She added: ''I definitely don't see myself as the toast of the town. But I've had a very successful week and I just consider myself to be so blessed to be able to do what I love.''

And the 37-year-old star was particularly happy with the response because she has been working so hard.

She said: ''We had all worked so hard on both of the collections. We've been doing really long days and nights with only three hours sleep here and there. But we got through it because we truly love what we do. We've achieved such a lot this week.''
