The controversial reality-TV couple have been plagued with pregnancy speculation since they left the show.
In the video, the pair are seen eating tacos when Martha quips that she’s eaten way too much.
Michael - who hit record on the camera without Martha’s knowledge - is then seen starting at her stomach, which causes her to question exactly what he is doing.
“What are you looking at now, huh,” said Martha.
“Your stomach, you said you feel so full, I want to see the pregnancy,” replied Michael.
The pair then giggle before the makeupartist realises the camera is recording.
“Are you f*cking stupid”, says Martha, before the video abruptly ends.
Martha made headlines last week after Sunrise host David Kochie Koch accused her of elbowing him at the Logies.
WATCH MARTHA SLAM SAM ARMYTAGE AND CALL HER A BULLY!
Kochie's co-host Sam Armytage, newsreader Natalie Barr and sports reporter Mark Beretta supported their colleague, leading Martha and Michael Brunelli to slam the Channel Seven veterans for "bullying".
However Martha denies 'elbowing' Kochie, saying she may have accidentally bumped into someone.
'I'm a person and I have feelings and Sam and Kochie have caused me so much stress and anxiety these past few days and I just feel like it's so unnecessary. Like for what, for ratings?' she said in her latest Instagram video.
'It's at the expense of my well-being and it's not fair!'
'He [Kochie] just thinks that because I was on a reality TV show that I don't deserve to get an apology from him or perhaps that I'm beneath him,' she continued.
'They've continued to mock me every morning on Sunrise, and I just feel like that goes to show you that they're no better than the thousands of trolling messages I've received over the last few months.'
