The 38-year-old singer shared a new photo of himself with eight-month-old Noah this week. Alongside the sweet snapshot, he wrote, "Out for a walk in Melbourne with my buddy… #chickmagnet #mbworldtour #australia #showday #tourfamily."
In the selfie, Michael can be seen holding Noah close to him, with the little boy resting his head on the superstar while sucking his dummy. The little boy is staring straight at the camera with his big blue eyes with his hair swept to one side - just like his daddy's.

Michael and Noah are in Australia with wife and mummy Luisana Lopilato, 26. Michael and Luisana tied the knot in Buenos Aires in March 2011, and welcomed their firstborn in Vancouver on 27 August 2013.
In November, Michael spoke about the "surreal" experience of becoming a father.
"It really wasn't what I thought it would be," he admitted during an interview with ITV's Daybreak.
"Everyone told me it would be this life-changing, massive, you know… but it was very surreal.
"Until you do it, you don't know, and now I know that we'd love to have three or four more… a litter."

The Canadian singer also spoke about how he maintains a happy marriage with Argentinian actress Luisana.
"I think that marriage is hard. I think that love is hard," Michael confessed. "I think that you've always got to try.
"In any relationship people fall in and out of love, you know. But it's just a matter of hoping that you don't fall out of love at the same time."
