Gabby Allen has been left upset over Kirstie Alley's fake tweets in a Celebrity Big Brother task.
In tonight's show, Big Brother gathers the group to announce a brand new challenge.
Big Brother explains: "Housemates, for today's task, you will all get to take part in a quiz, where you will be sown social media comments that have been written by the Big Brother viewers.
"Each comment will have the name of the housemate that it is about blanked out. As a team you must come to a collective decision as to who each comment is about."
However, they're unaware that all the messages are in fact fake.
As part of a new twist, Kirstie Alley was called to the Diary Room yesterday and asked to make up tweets about her fellow housemates.
"You are not sexy so stop batting your eyes at all the boys #looklikeanidiot," read one comment, which Kirstie had written about Gabby Allen.
On finding out about the twist, Gabby wasn't too happy.
"I've had a lot of trolls and nasty comments before in the past," Gabby tells Big Brother in the Diary Room. "It takes a lot of self love and work to really get over them and take it on the chin and brush it off.
"When you're in here and its so intense, hearing things like that aren't ideal. I do suffer with self confidence issues, I've spoken openly about it before, like wanting work done because I feel I don't suffice in areas that maybe I should. There are things I've considered getting done in order to make myself sexier or prettier."
She added: "So to have something like that, even if it was a fake comment I was still upset about it... that's a bit s**t."
Other comments written by Kirstie included "Bloody hell, put a shirt on, no one wants fur in their crisps," about Hardeep.
And Nick was told by a 'viewer': "You are more boring than watching paint drying, being generous."
The task and all the fallout will air in Thursday night's highlights show.
Elsewhere in this evening's episode, Kirstie tells Hardeep how the American’s do cocktails, Kirstie talks about her celeb crush and housemates discuss who should pay on the first date.
Celebrity Big Brother 2018 continues nightly on Channel 5.
