Rachel's name is the latest to crop up when it comes to CBB rumours and according to reports, show bosses are hoping the six figure sum will help to secure the reality star's place on the show.
It's thought show bosses are keen to get her into the house, as she had a turbulent relationship with former CBB star David McIntosh (who she shares her son, Logan, with) and could tell all about their time together on camera.
Rachel (who is preparing to launch her own Fitness magazine, Going For Gold) had been rumoured to appear on I'm A Celebrity... Get Me Out Of Here! but she dismissed the claims when Reveal caught up with her earlier this month.
Instead, Rachel hinted she could be returning to our screens on a different show. She said: "That was a massive rumour, but there might be something else..."
A source exclusively told The Mirror that Rachel's representatives are keen for her to appear on the Channel 5 reality show too.
"Her representatives have been wanting her to enter since Love Island," they 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
"She's incredibly funny and opinionated - she's not afraid of confrontation and will be good for the show."
Rachel starred on the comeback series of Love Island back in July. She is the niece of pro athlete Linford Christie and formerly won the title of Miss England in 2009, before relinquishing her crown.
If she does head into the CBB house, those that could be joining her are so far rumoured to be TOWIE star Gemma Collins, Danniella Westbrook, former Hollyoaks star Stephanie Davis and Geordie Shore star Gary Beadle's ex Lillie Lexie Gregg.
