As her curves continue to shrink, Catherine Zeta Jones has had to find herself a whole new wardrobe.

And who better to inspire her than stylish friend and fellow ex-pat Victoria Beckham?

The 40-year-old has seen her figure become toned and athletic following two months of dancing nearly every night in Broadway musical A Little Night Music.

Inspired by Posh? A skinny Catherine Zeta Jones stepped out in this Victoria Beckham-style leather outfit in New York yesterday

Yesterday Catherine headed to the show from her New York apartment in black leather jeans and jacket, with a military style cap.

Teamed with a pair of oversized sunglasses, she looked like Posh's mirror image.

It isn't the first time Catherine appears to have taken inspiration from Victoria.

In December the mother-of-two wore a leather and fur combination within days of Victoria donning the same.

Catherine is used to dressing to accommodate her changing figure.

She has told how she 'ate for Wales' when pregnant with son, Dylan, now seven, which saw her balloon to 13st.

After the birth of daughter Carys five years ago, she used a tough dance-based routine from her movie Chicago to whittle herself into a leaner shape.

After that she became curvy again - so curvy that there was speculation she had had breast enlargement surgery. Her publicist refused to comment on the rumours.

Then, in June 2008, she cut a remarkably lean figure while on the set of her film The Rebound.

Catherine and husband Michael Douglas recently moved to New York from Bermuda; they plan to stay for the next two years.
