USA international Maurice Edu's girlfriend Lauren McDonald was pictured in lingerie on the website of an agency calling itself the 'Luxurious Collection' and advertising £1,200-a-night escorts.
But the 25-year-old model and beauty parlour owner is furious that an image of her taken on a shoot has been used by the company.
"I'm absolutely disgusted. I don't know who is behind this but I could maybe guess because some people have a grudge against me," she told the Daily Record.
"It's ridiculous to think I would do such a thing. I know lots of people in Glasgow and I have a thriving business, which I would never put at risk.
"This is really damaging for me, even though it's not true. I don't want anyone to read a story in the Record and think there's any truth in it."
McDonald, who has been in an on-off-on again relationship with Edu for nearly two years, added that she has instructed lawyers to get the photo removed.
"I have told my representatives to get on to this and the photograph will be taken down as soon as possible.
"My lawyer will also be looking at it and we'll sue the people behind it."
