Rachel Stevens has reportedly been axed as the face of Pretty Polly.
The sexy singer signed a 100,000GBP deal with the hosiery giants last August, but bosses have decide to end her contract as she wasn't making a great impact on the market.
An insider told Britain's Daily Mirror newspaper: "Rachel's gorgeous but using her in the campaign didn't have the impact on sales people had hoped for.
"She's very petite and perhaps people don't associate her with sexy lingerie shoots."
It had been rumoured bosses were not happy with the 5ft 3ins star - who followed in the footsteps of models Jemma Kidd and Tania Strecker when she signed the lucrative contract - when she posed for a raunchy magazine shoot in a rival company's underwear.
It is now thought Pretty Polly executives want British R'n'B star Jamelia to replace Rachel. The insider added: "They're really desperate to sign up Jamelia to take over from Rachel.
She's so hot at the moment, especially after her three Mobo nominations.
"They're in the process of thrashing out a deal but Jamelia won't put her name to just any old campaign."
