WATCH: Odd couple! Jackie O reveals secret 'hook-up' with Nick Giannopoulos

We can always rely on Jackie O for an overshare… and her latest piece of goss really had us shocked!

While quizzing The Inbetweeners cast for KIIS FM, 39-year-old Jackie revealed she'd "hooked up" with Aussie comic Nick Giannopoulos (The Wog Boy)… in the back-seat of his car! Who said chivalry was dead?

Kyle also made sure listeners were fully aware he'd been "teasing Jackie ever since!" Hear Jackie describe the unlikely celeb rendezvous above!

But don't think Jackie's the only who suffered a strong bout of TMI today!

Talking health with Sydney Swans player Ryan O'Keefe, King Kyle revealed that no amount of bedroom aerobics with GF Imogen Anthony has increased his fitness.

"I'm having sex every day," Kyle said. "And look here – no improvement!"

Thanks for that, Kyle.
