A fan at the show confirmed that the two were together all night, writing on a Facebook Fan page, "Can confirm Martha and Jessika's brother were together at Melbourne Fashion week.
"They were taking photos together and being cuddled up, with Michael nowhere to be seen."
The source also revealed that Martha was asked if she and Power were now an item, and her answer was highly suspicious.
"I overheard someone ask if they're together and she said, 'We're not allowed to say anything,'" said the source.
It comes after Martha revealed she and Jessika are no longer friends, despite being close on the show.
Speaking on Nova 96.9 recently, Martha told the radio hosts that her and Jess only "speak here and there".
Martha posted a photo with MAFS husband Michael on Instagram 17 hours ago, where it seems like they're enjoying a romantic dinner together.
"The perfect end to a perfect week....... @mbrunelli 😜" wrote Martha in the caption.
Who even knows anymore??
