Abbey Clancy pulled out of a TV appearance booked for today in the wake of allegations about her footballer fiance Peter Crouch.
Clancy, 24, was supposed to present live Tuesday fashion slots on ITV1 show This Morning.
But she cancelled today's appearance and it is not yet known when she will return to the programme.
The model was pictured without her engagement ring while filming her E4 reality TV show Great British Hairdresser after pictures emerged of Crouch, 29, apparently flirting with women in France.
The pictures appeared to show Crouch touching the thigh of a woman in a French nightclub.
Crouch and his fiancee, who have a mansion in Weybridge, Surrey, are said to have held crisis talks about their future.
A This Morning spokeswoman confirmed Clancy had pulled out of today's fashion slot and added: "We are keeping in touch with her each week."
Tottenham striker Crouch is in Switzerland for a Champions League qualifier tonight.
