Mone, founder and co-owner of lingerie firm MJM International, lined up with Celtic stars Gary Hooper and Thomas Rogne to promote a fundraising fashion show in aid of breast cancer research.
The show, which is to take place on 14 November, is billed as Celtic Charity Fund's Fashion Show, with Breast Cancer Care Scotland the main beneficiary of the event.
Mone said: "I'm delighted to be involved in the Celtic Fashion Show to support Breast Cancer Care, a magnificent cause.
"I'm sure I'll teach them how to strut their stuff just like our Ultimo girls!"
Members of Celtic first team will also appear in the show, with some players volunteering to step up onto the catwalk.
Celtic striker Anthony Stokes said: "I was delighted to be asked to take part in this event.
"Breast Cancer Care Scotland is an incredibly deserving charity and I hope we can raise as much as possible for them."
Colin Graham, area fundraising manager for Breast Cancer Care Scotland & Northern Ireland, added: "The money raised from this event will help ensure that no-one need face a breast cancer diagnosis alone."
