After a week of ups and downs, we're not sure if Gabi Grecko's latest revelations will help or hinder her relationship with fiancé Geoffrey Edelsten.

The 25-year-old model took to social media to share the real reason she is with the 71-year-old entrepreneur, writing: "Geoff is just a piece of ass and I'm using him for sex."

The TMI comments came the same day as the on-again, off-again pair confirmed they were back together after a brief split.

However it's not the first time the controversial couple have divulged details of their bedroom antics, with Geoffrey telling the Daily Mail yesterday that the wedding was back on and that they had resolved their differences between the sheets.

"We went out for dinner, watched a movie at home with Angelina Jolie and Winona Ryder called Girl, Interrupted, and resolved our differences in bed," he said.

The entrepreneur had just the day before described his 25-year-old as 'volatile' and said she 'keeps changing her mind' as reasons for their split, but despite that the pair just can't stay away from each other.

"I still stand by what I said, she is extremely volatile and keeps changing her mind about certain matters but we're happily together again," he confirmed.

The pair first went pubic with their relationship in May 2014 and despite a number of splits they became engaged with a very public proposal at the Melbourne Cup in November.
