The Argentinian model and actress was chosen to front the underwear brand's new campaign last October, causing sales to increase by a staggering 37%.

Luisana is currently promoting Ultimo's famous bust boosting OMG bra, right in time for Valentine's Day.
The OMG brassiere was made famous by Julia Roberts in Oscar winning film 'Erin Brockovich' in 2000.

The gel-filled bra can boost a woman's bust by up to two cup sizes and it's one of Ultimo's most successful products.

'The Miracle OMG is a real showstopper and when you have worn it once you will be amazed' said the lingerie company founder Michelle Mone – 'not only by the result but also how great it feels to wear. It's not called the OMG for nothing.'
