Gabi and Geoffrey Edelsten have broken up after little more than one month of marriage. Or have they?

Grecko posted a photo of her ringless hand on Instagram, lamenting the split.

“No longer Mrs. Edelsten,” she said, adding a broken heart emoticon.

But just an hour later, the model posted a video on her account of her putting her wedding ring back on her finger, leading many to ponder whether it was all just a publicity stunt.

The pair wed in Melbourne on June 11 this year.

They will both appear on Channel 9’s reality show Celebrity Apprentice.
