Taking to Instagram on Monday evening, Michael shared a shot of him cradling his newborn nephew.
"So I became an uncle this week!! Everyone meet Luca James Brunelli," he captioned it.
But it didn't stop fans ribbing him in the comments, saying that it would be he and his Kim Kardashian West lookalike girlfriend who would be next.
And it seems Michael would be up for it, tagging Martha in some of the comments.
Last week, Martha revealed that the couple plan to name their firstborn Psalm after Kimye's youngest son.
The newborn might take the couple's minds of the drama that has been going down in recent weeks.
It all started when Sunrise's David "Kochie" Koch and Mark Beretta claimed that Martha bruised them when she elbowed them in the ribs at the 61st annual TV Week Logie Awards in the Gold Coast.
Natalie Barr also said Martha gave her "attitude".
Martha has denied the claims and said she believes the Seven stars are looking to boost their ratings on the back of the Nine reality hit.
