First Victoria Beckham, then Elle Macpherson and now Katherine Jenkins is the latest celebrity to wear Posh Spice’s strapless black dress.  Only this time Katherine uses her own tweet page to show off, her stunning look.

But few would deny that the classical singer pulls off the dress the best thanks to her voluptuous curves in all the right places.

Katherine appeared to be going for the Jessica Rabbit look in the skin-tight £1,500 black Victoria Beckham Collection dress, which she teamed with a £490 pair of Yves Saint Laurent Tribute pumps.

Katherine posted pictures of her Beckham dress and another black Dolce & Gabbana gown on her micro-blogging page as she mused over her fashion choices.

She wrote: ‘Help! What shall I wear tonight?! This dress by Victoria Beckham with beautiful earrings by Erickson Beamon or this one from Dolce & Gabbana? Isn’t the butterfly cute?!  Will Tweet a pic of me in the winning dress.’

After receiving overwhelming positive feedback for the Beckham dress, Katherine plumped for the form-fitting gown, which has been seen on Elle Macpherson in recent months.

She added: ‘Was pretty close actually but Victoria’s seemed to have the advantage.’ >Celeb
