I’m not sure if this is the instance you’re talking about but there was a time when Richard Madeley asked her ‘are you rich?’ on a morning breakfast programme (Good Morning Britain?) and she bounced back cockily/smugly with ‘are YOU rich?’ - clearly something she’d rehearsed over and over again in her head - and he was completely unphased by it, if I remember rightly he just shrugged and said ‘well, yeah, but are you?’. She clearly hadn’t expected such a confident response back and you could visibly see her flounder
that was also incredibly cringey!
