The 24-year-old models the three new lingerie sets released in time for V-Day, and follows in the footsteps of previous Ultimo faces (or bodies) Kelly Brook, Rachel Hunter and Sarah Harding.
"I loved shooting the Ultimo campaign and usually have to wear plain underwear when I'm filming so it was incredible to be wearing such gorgeous lingerie," says Luisana.
"The new collection is not only very sophisticated and feminine but feels comfortable as well so that you have that confidence from the inside out."
Looks like Mr Bublé's set for a good Valentine's Day this year...
