It all kicks off when Monique pulls Bachelor Matt to the side for a very flirty chat, and Nichole can't handle it.
"Way to p**s Nichole off," Nichole said as she watched, talking about herself in third person.
Nichole, who was sitting next to Rachael, then said about Monique: "She thinks she's better than us."
Which is when Nichole then lost her cool and stormed off, saying: "I'm f***ing over it."
She added: "I'm f***ing done with it!"
Watch the next episode to find out whether Nichole is gone for good.
