The Argentinean model, who is expecting her first child with her hubby Michael, shared a gorgeous picture of her tummy on Facebook, joking that it is a "super belly".
In the black and white photograph, Luisana is wearing a bra, white tailored jacket and a pair of jeans. She has placed her right hand on top of her bump and is smiling at the camera.
Alongside it, she wrote a message to her fans in Argentinian. Roughly translated, it reads: "I'm used to the super belly and now we're impatient to see #babybuble!"
Luisana is 39 weeks pregnant with their son and, last week, Michael sparked rumours that she had gone into labour by cancelling a pre-arranged TV appearance on America's Today.
But after recording a video for viewers to explain his absence, he has since admitted it was a false alarm after Luisana started having stomach pains.
Speaking to Associated Press, Michael revealed: "We had a false alarm a couple of days ago and she had about seven hours of labour so we know that it could happen at any time."
He added: "Neither one of us are anxious, we're just excited. We can't wait to know what it's like, we can't wait to meet this little guy."
