WATCH: MARTHA ON THAT WINE-THROWING INCIDENT
But they were always worn behind closed doors.
On Tuesday evening, the 30-year-old wore a white face mask to Woolworth in search of earplugs, because a neighbour's baby was crying loudly.
"Desperate time. We're so maternal," Martha and a friend joked as they filmed themselves for Instagram, combing the aisles for Play-Doh to use as earplugs.
Apparently they couldn't get their hands on the real deal.
The reality star then got distracted, and began eating grapes direct from the display case.
"You're not taking that mask off are you, ledg [legend]?" her friend laughed.
"Are you stealing grapes? MAFS doesn't pay, huh?"
Prior to their supermarket dash, Martha shared a clip of herself on the couch, wearing the mask, captioned, "Have kids they said, it's rewarding..."
Looks like her "husband" Michael Brunelli won't be becoming a father anytime soon!
