Tila Tequila has been removed from the Celebrity Big Brother house less than 24 hours after she joined it after Channel 5 discovered an offensive post from her Facebook page.
CBB bosses took the decision to boot Tila out after an image of her dressed in Nazi uniform was found on her social media account.
The post – which shows Tila wearing a swastika armband and military cap while holding a gun and posing outside a Nazi death camp – was allegedly uploaded to Facebook in December 2013.
Tila is also thought to have made several comments praising Hitler, calling him a "brilliant artist" and, according to some reports, comparing herself to him.
Channel 5 reps said in a statement: "Unfortunately, Channel 5 and Endemol did not know about the views and attitudes Tila had expressed in social media postings prior to her involvement in Celebrity Big Brother.
"When they were brought to our attention, she was called to the Diary Room for a discussion with producers and was subsequently removed from the house.
"The views Tila had expressed, and permitted to remain uncorrected, are totally unacceptable and, accordingly, her continued involvement in the programme was untenable."
Tila herself has not yet commented on the allegations.
