Owner Michelle Mone, who was awarded an OBE in 2010, was delighted to get Luisana on board.
“Michael Buble’s wife Luisana is one of our biggest international stars and the response we have had has been phenomenal,” she said.
“It took me a long time to get her but I refused to give up.”
The collection is to be launched ahead of Valentine’s Day.
It features separates in seductive black lace, ivory and pretty shades of green and pink, all designed to “reveal the inner temptress”.
