Model Jasmine reportedly had a six-month fling with the TV mogul, and is now set to blab in the Celebrity Big Brother house.
According to the Daily Star, Simon still has feelings for Jasmine, meaning he'll be "glued" to the upcoming series.
“Simon’s secretly still very fond of her which drives some of his current squeezes mad," a friend claimed to the newspaper. “Although he is pleased for her that she’s going into the Big Brother house he is also wondering what she’s going to say about him. She’s a free spirit and very chatty.”
However another source claimed to the Daily Mail that Jasmine and Simon had come to a "privacy truce", ensuring that details of their romance are never made public.
The source said: "She has never spilled the beans on Simon because they came to a mutual understanding. That’s not going to change."
The new series of Celebrity Big Brother starts on Wednesday on Channel 5.
