Elle Macpherson is Posh's number one fan

Elle Macpherson scores a Victoria Beckham style hat trick

It's official! Elle Macpherson is Victoria Beckham's number one fashion fan.

Just a day after stepping out in Posh's autumn/winter '09 Carmontelle grey dress, the supermodel was back in VB, yet again, this time the Giral strapless black silk dress.

Looking uber-elegant, Macpherson kept things simple, teaming the dress with oversized shades and purple patent courts.

A particular favourite of Mrs B's, she wore the purple Giral for her appearance on American Idol in Denver last week, and then changed into the black version to jet back to LA.

Elle is currently filming new TV show, The Beautiful Life, in New York, and has stepped onto the set in Beckham dresses for two consecutive days.

Her penchant for Posh style started back in June though, when she wore a spring '09 figure-hugging black bandeau for a party in LA.

The supermodel has clearly been stocking up, but let us know your favourite of her Beckham style moments in the comments box below. Is it the black strapless, the grey Carmontelle or the chic Giral? The choice is yours!
