There's a really good chance Jackie O just exposed the winner of The Bachelor.

WARNING: THIS POST MAY CONTAIN SPOILERS. NOW IS YOUR CHANCE TO GO BACK. YOU’VE BEEN WARNED.

Another day, another Bachelor winner conspiracy theory.

We’re down to the final two girls – Nikki and Alex – and we’re so close to finding out who the winner is that we can ALMOST TASTE IT.

So, naturally, we’re soaking up every possible bit of information about who the final girl left standing is going to be. Don’t judge us.

Nikki and Alex both appeared on The Kyle and Jackie O Show this morning, and of course, the conversation turned to the various theories about which girl will be crowned the winner.

Cue Jackie O letting slip a potentially MAJOR spoiler.

"We had a pap on yesterday who followed you to Bali and he said he worked out who had won," she began.

Last year's runner-up Lana tells all on the latest episode of Bach Chat. Post continues... 

"The next day after the finale was filmed he saw one of your luggage pieces - he’d memorised who had what luggage - and he saw one of your [bags] coming out of Richie’s hotel room. That’s how he worked out who the winner was."

The pictures have been circulating online this morning, and point to (SPOILER ALERT) single mum Alex being the winner. Both Richie and Alex's bags - which they have both previously been papped carrying - in the back of the same van.

But the girls weren't about to give the game away, with both confirming they've heard "so many theories" about which one of them wins.

Jackie offered up another theory, telling Nikki that she was "too quiet" to be the winner.

"You're very quiet, Nikki! Alex is doing most of the talking and answering all the questions!" she said.

Of course, Kyle couldn't resist trying to trip the girls up with questions about...you guessed it...their sex lives.

"Can either of you confirm or deny this rumour? We've heard a rumour that Richie finishes very quickly," he asked.

"I don't know..." a sly Alex replied.

"I wouldn't have a bloody clue!"

OH MY GOODNESS! THE SUSPENSE IS KILLING US...but we'll just have to wait and see.

SCROLL THROUGH the gallery to see who is left in the competition for Richie's heart. Post continues...
