"I’ve been stitched up in a few of these," he stated in the comments.
In a typically dry response, Martha quipped: "@mbrunelli who’s to blame…"
Other fans, meanwhile, took to the comments to share their support.
"Lockdown is making people cute," remarked one.
"U guys are too cute 💘x," messaged another.
"Lockdown goals 🔥," a third stated.
This isn't Martha and Michael's first lockdown together.
Speaking to Now To Love during the pandemic's first wave, Martha admitted she and her partner had gone through the range of emotions many couples did.
"We've had our ups and downs," she told the publication.
"The beginning was fun – we were like 'Ok this is something different'. Then we reached a stage where we were bored, then we were frustrated, then we went back and were like 'It's alright, we don't mind it, things are getting better,' and then bored and frustrated. It's just been up and down."
As one of the few remaining MAFS couples still together, Martha and Michael have proved that the show can be a romantic success.
“I always say Michael and I meeting was like fate and I know it's so cheesy because I hate saying cheesy s*** like that but I really think it is otherwise it doesn't really make sense,” Martha told the Shameless podcast in February 2021.
“I think we were going to meet no matter what. Michael actually in Melbourne lives five minutes away from my parents' house. No matter what happened, in this lifetime we were going to meet and be together.”
