Since making a shock exit from the CBB house last night, Trisha has slammed Sarah for her behaviour.
In another YouTube rant, Trisha has threatened to expose a secret about the 35-year-old.
She said: "Something hasn't been revealed on the show that I know about Sarah, not nothing too personal, but all I know is that she is in for a rude awakening when she gets out of that house."

Trisha then told her fans to watch the show tonight, which will feature her departure from the house.
She said: "We will see if they sort this s*** out, and if they do, I won't have to make the video I want to make.
"But they have to make it right with me because some s*** went down and that is it."
