Katie Price faces losing £3m (€3.5m) in endorsements deals following her wild behaviour since splitting from Peter Andre.
The glamour model - who is also known as Jordan - has been partying heavily since splitting from her husband and some of her lucrative contracts are believed to be under review.
A source close to the mother-of-three - whose deals include a £2m (€2.3m) lingerie and £1m (€1.15m) bed linen contract - told the Daily Mirror newspaper: "Katie has built a fantastically marketable career as Katie Price, mother of three children and a role model to young girls.
"She has admitted she wants to go back to being Jordan, and her behaviour since splitting from Pete has been wild to say the least. She's gone back to her pneumatic glamour model roots, getting drunk and posing erotically.
"From being a respected self-made entrepreneur, some people - young women and mothers in particular - have turned against her."
Katie, 31, is currently holidaying in Ibiza, where she has enjoyed several wild evenings out and been spotted kissing model Anthony Lowther.
She is also alleged to have threatened to "cut up" a female clubber. Although she initially claimed to be devastated by the split with Pete - who is currently on holiday in Cyprus with the children they raise together, seven-year-old Harvey, Junior, four, and 23-month-old Princess Tiaamii -
Katie has had a tattoo of his name on her wrist crossed out.
She splashed out £85 (€99) to hide his name, reportedly telling friends: "I want to show Peter's no longer part of my life."
