It follows a huge row between her and Natalie Nunn.
The pair clashed in the bathroom after Natalie claimed Gabby was excluding her and Rodrigo Alves from her workouts.
Gabby denied the claims, as Natalie accused: "You're only telling the boys when you're working out."
The row then escalated as the girls began to shout at one another - before Gabby retreated to the Diary Room.
In tears, she cried to Big Brother: "I want to go home."
Gabby said of Natalie's accusations: "I've not left anyone out. She's making out I'm deliberately targeting anyone who is not a boy.
"I don't know what she's trying to imply."
The Love Islander concluded: "I don't want to be in the house with her."
It's the second time that Gabby has been left in tears by US reality star Natalie.
"It's the way everything's said. Being put on the spot stresses me out," Gabby told Dan Osborne of Natalie in Tuesday night's latest highlights.
He replied: "That's just the way she is. That's her character, that's the way she speaks."
Gabby then admitted: "I just feel intimidated."
Other housemates have also clashed with Natalie, who faces eviction on Friday after receiving eight nominations, the most of any housemate.
But Natalie protested her questioning nature, saying: "Why is it so f**king tense? Is your storm that bad? Then I really want to know
"I would like to know who you guys are, I'm living with you, I'm sleeping with you guys, I'm showering with you guys. I would like to know and I'm going to ask."
