Holly Valance rocks tight-fitting black leather dress

HOLLY Valance rocks a tight-fitting black leather dress at a star-studded bash.

The Aussie beauty, 29, wore the figure-hugging halterneck frock as she attended a party for the Government’s GREAT Campaign, which aims to promote the UK abroad during the Olympics, last night.

On her arm at the Royal Academy of Arts in central London was her smartly-dressed fiancé Nick Candy.

The former Neighbours star got engaged to the 38-year-old property tycoon last December.

And after the romantic proposal in the Maldives she quickly dropped a dress size.

But now she is said to have ditched her diet because "Nick loves her the way she is".

Engaged ... Holly Valance and Nick Candy

A pal reportedly told Closer magazine: "Holly's sick of dieting. She's back to a size 12-14, but she's naturally curvy and would prefer to be comfortable than obsess over being skinny.

"She went on the Clean & Lean Diet a few months ago and it worked, but she loved her food and felt miserable. And she says Nick loves her the way she is anyway."

The Duchess of Cambridge, supermodel Lily Cole, designer Stella McCartney and artist Tracey Emin were among a host of prestigious guests at last night's event.
