Josie, who won the 2010 series of Big Brother, took to Twitter and shared her views on Katie after the contestant was told by BB to summarise her frank thoughts on the housemates before picking the "dullest" two.
But after watching her in action, Josie told her followers: "Katie Hopkins is coming over proper false, like she's acting sort of weird....."
Josie wasn't the only celebrity to admit they were perplexed by Katie's behaviour either. Michelle Heaton asked her fans: "#katiehopkins is acting a bit odd, no?"
At the start of last night's launch show, Katie was first to enter the CBB house before being given her secret mission by Big Brother.
Katie Hopkins is coming over proper false like she's acting sort of weird.....— Josie Gibson (@Josiestweet) January 7, 2015
In keeping with this year's Twisted Fairytale theme, she was challenged to become an Enchanted Mirror for the evening, hiding behind a two-sided mirror to observe the other stars arriving and give her honest opinion on them.
She then had to choose her two most boring housemates - Chloe Goodman and Alexander O'Neal. The pair were then told they face eviction, however BB made it appear as though they had made the decision.
Although Josie and Michelle were unsure about Katie's reaction to the task, former Celebrity Big Brother winner Charlotte Crosby is looking forward to seeing more of the former Apprentice star.
"I think Katie Hopkins will make this!I" she tweeted.
