Olivia Palermo photographed by husband Johannes

Olivia Palermo and Johannes Huebl are one of the most stylish couples on the planet - and he's snapped her for the jewellery house Piaget's new campaign. Read on to see if he's got rose-tinted glasses...

Olivia Palermo is one of our all-time favourite fashion plates. We love her canny way with accessories, and we've long admired her knack for jewellery in particular - she always looks glamorous, but never OTT. So we're loving the fact that her equally fabulous husband, model, Johannes Huebl, has made a foray into photography to shoot her latest ad campaign, for fine jewellery house Piaget.

The maison's Possession collection is one of the house's iconic lines - it was first unveiled in 1990 and its classic ring design features a second rotating ring that you can play around with - perfect for date-night nerves, high-drama meeting moments, as a glamorous version of a meditation aide (or 'talisman', as the house call it)...

The new collection features coloured gemstones for the first time (a very big deal in the land of fine jewels, gem lovers!). During the campaign shoot, Olivia played a fashion version of that old chestnut, the word-assocation game, telling us what each colour represents to her.

“Colour is very much something I enjoy in life. I love that it was incorporated in the new collection,” she says. “I think within the collection you see the different ways women can wear the Possession pieces and how it gives them confidence.”
