Michelle Mone has launched her first collection for Ultimo since the exit of her former husband.

The new vintage inspired lingerie collection is modelled by Luisana Lopilato, who is married to singer Michael Bublé. She was four months pregnant when she did the shoot in New York for the spring summer 2013 collection.

Ultimo creator Michelle Mone said: “Luisana looks absolutely beautiful in our new summer collection. She is the stunning Mum to be and looks effortlessly sexy as always.

"It’s fantastic that Luisana is showing all mothers-to-be that you can look hot if not hotter being pregnant.

"We had such a great time shooting in New York, it’s been a dream of mine to shoot there since I started Ultimo, the timing couldn't have been anymore perfect as this is my first collection since I got my Ultimo baby back. "

Argentine model and actress Luisana said: “I really enjoyed the shoot in New York and working with Michelle and the amazing Ultimo team again. I love wearing Ultimo as they have Lingerie for Everyday Wear, Solution Bras, Fashion Collections and the very Sexy Black Label. I'd like to thank Michelle for being so supportive in doing this sexy shoot whilst I'm pregnant. I can't wait for our baby boy to arrive!"

The new collection is said to be a ‘twisted vintage’ look, inspired by Farrah Fawcett and the glamour of the 1970s.

The 41-year-old Scots businesswoman is now sole owner of her underwear empire, after coming to an agreement with her former husband earlier this year.

Michael and Michelle Mone founded MJM International together in 1996 and had been in dispute over who should take ownership following their split in 2011. They had been married for 19 years and have three children together - Rebecca, 19, Declan, 15, and Bethany, 11.

The new Spring/Summer Fashion 2013 collection, as modelled by Luisana Lopilato, is available from Debenhams, Next, House of Fraser, ASOS and www.ultimo.co.uk
