Description: Actress Luisana Lopilato shows off the latest Ultimo collection in time for Valentine’s Day. The blonde actress, wife to singer Michael Buble and a successful actress in her home country of Argentina, signed up as the face of the brand for a two-year stint in October last year. The Argentinian bombshell dazzles in the jaw-dropping new collection from the UK’s leading lingerie designer created by Michelle Mone OBE, just in time to make this Valentine's day extra special for women and lucky men alike. Since then, sales have rocketed by 37 per cent - a spike that Ultimo founder and CEO Michelle Mone attributes in part to the Lopilato effect. The 24-year-old actress has over one million Twitter followers and is a huge star in her home country of Argentina.
