The 24-year-old cancelled her fashion slot on ITV1's This Morning after worrying about the "scrutiny" she would be under, reports The Sun.
Fresh claims emerged over the weekend that England star Crouch was seen kissing and flirting with several women in a nightclub while in the French Riviera.
Clancy has since been spotted without her engagement ring on, as she filmed for E4 show Great British Hairdresser.
"She asked him how many more revelations there will be," a source told the paper. "She couldn't face This Morning - the scrutiny would be too much."
