Abbey Clancy is reportedly in a "bra war" with Ultimo owner Michelle Mone OBE.
The wife of footballer Peter Crouch has ticked off Mone by modelling in her underwear in advertisements for other companies, the Daily Star reported.
Clancy has recently appeared in her smalls for Scholl and Veet campaigns, despite being midway through her contract with Ultimo.
According to sources, Clancy is two thirds of the way through her contract, but it is clear that the relationship between them has completely broken down.
It was also revealed that a joint statement from the model and Ultimo simply stated that both parties have decided to terminate the contract due to creative differences.
Insiders told The Sun that Mone was unhappy about the picture of the model in her knickers for Veet, who thinks she's done nothing wrong.
