Geoffrey Edelsten's flamboyant fiancée Gabi Grecko took to Instagram this week to show off her new 'do ahead of a trip to Sydney.

The 25-year-old, who frequently changes her hair, is now sporting long curly ginger locks, "getting used to the new hair color," she wrote.

The US-born model and DJ also posted a selfie of her airport ensemble ahead of her flight.

When most people think about dressing for a flight, they opt for comfort, but Gabi instead opted for a seriously low-cut black blazer - sans bra - a pair of barely-there denim hot pants and thigh-high stockings.

Gabi has also raised eyebrows this week with a number of posts of her hand sporting what appears to be a wedding band.

In one video, which showed an extreme close-up of a diamond band sitting underneath her engagement ring, which she captioned "waiting", believed to be in reference to his impending divorce from ex-wife Brynne Edelsten.

The ring appeared to be her 71-year-old beau's wedding band from the marriage to Brynne, however she confirmed it is actually a different ring.

"It's similar to the wedding ring but it had bigger diamonds [than this ring]," she told the Daily Mail.
