London, Sep 17 - German supermodel Heidi Klum, who is expecting her fourth child, has pulled out of an appearance at designer Ann Taylor's collection preview at New York Fashion Week Thursday night because she could go into labour at any moment.

Klum was recently unveiled as the new face of Taylor's clothing label, but she will be skipping his show, awaiting the imminent arrival of her child with singer husband Seal in LA, reports contactmusic.com.

'(Klum) won't be able to make it to the show because she is due any day now,' said a representative for Taylor.

The baby will be Klum's fourth. She is mother to daughter Leni, five, from a previous relationship, in addition to sons Henry, four, and Johan, two from Seal.
