Earlier today, the reality star became the latest name rumoured for the Channel 5 show's new series in January.
It was said show bosses had offered Rachel £300,000 to join the lineup, but taking to Twitter, she seems to have shut down the claims, insisting they are just rumours.
Without directly referring to CBB, Rachel shared a laughing emoji, along with the tweet: "This is not true all these rumours."

Her post comes after reports suggested she was the latest celebrity to be heading into the CBB house. According to The Mirror, producers had wanted Rachel, hoping she would tell all on her rocky relationship with the Gladiators star and Kelly Brook's former flame David McIntosh.
He and Rachel dated in the past and share a son, Logan, together.
A source also told the paper that the starlet's representatives had been keen for her to sign up. "They have been wanting her to enter since Love Island," the source revealed. "They felt it was a one dimensional show and that the CBB house, along with the hefty pay packet they're offering, will see her at her best."
This isn't the first time Rachel has had to dismiss claims she is starring on another reality show, as she was pinpointed for I'm A Celebrity before the current series began.
Earlier this month, Rachel told Reveal she would not be going into the jungle and admitted it was a "massive rumour". However, she did add that she has plans to appear on something similar soon, telling us: "There might be something else..."
If she has now ruled out CBB, could Rachel mean The Jump?
We guess only time will tell!
