The Strictly Come Dancing winner is said to have shown a blatant disregard for the rules after taking part in the campaign for Clairol.
The ads saw the 34-year-old jumping into a leotard with her hair freshly dyed.
But the heads of the Beeb thought the scenes were too similar to the format of BBC Three’s Glow Up show, which sees makeup artists taking part in challenges in an effort to show off their skills.
According to the rules of the BBC, actors or artists under contract with them cannot appear in any advertisement which “imitates or reproduces their roles on air for the BBC”.
Stacey’s time on the show ended quietly after being seamlessly replaced after two sets.
Maya Jama, 26, took over the role for her.
A BBC source told The Sun: ‘Stacey could have made it look like she was stepping away from the show on her own accord, but in reality she was not asked to stay because the BBC was furious against Clairol.
“They are fed up with people using their platform to go out and earn private money.
“It was a sticky situation because she does other things for the BBC, but they decided she would lose her Glow Up contract. “
The source revealed that the final decision was to remove Stacey from the Glow Up show, but allow her to continue with her other projects.
The revelation comes after last month’s news that Nick Knowles had passed the bar with his participation in a Shreddies campaign.
The DIY SOS star is said to be involved in crisis talks with the broadcaster after an advertisement in which he played a builder.
It was later revealed that the 58-year-old would keep his job as host of the show despite allegedly ‘breaking the rules’ by appearing in the ad.
At the time, Nick said, “I’ve always said DIY SOS is more than just presentation work for me, it’s part of me.
“It’s my heart and working for the BBC for over 22 years is something I have never taken for granted. “
