The 25 year old is the face (or should that be bum and boobs?) for well known undies brand Ultimo.
It's believed that after Luisana gives birth she can't wait to get back to modelling.
However, Luisana won't be able to indulge in any more photo shoots like this for a while since she is now expecting a baby Buble!
Michael recently opened up about his fears when it came to having their first baby, saying he thought the process could take ages and maybe not even happen at all.
The star said: "I honestly thought that we'd have to try for a year or longer."
"I'd even accepted that not every couple can have a baby naturally and may we'd adopt and that would be okay with me too."
However, now Luisana is pregnant Michael couldn't be more excited.
The father-to-be added: "Yesterday was the first day she ever felt him kick, she was really excited about it, it's amazing, it trips me out."
"For her, it's more real as he's inside her, whereas for me it's very romantic right now. I love how close we are, and we can't wait to do it again and again and again."
Woah there Buble, let's just get this one out the way first, yeah?!
