But despite the media reports that continue to surface daily about her partner's romance with model Vanessa Perroncel – the footballer was stripped of his England captaincy on Friday – HELLO! can reveal Toni has vowed to stand by her man.
In this week's issue – number 1110 – close friends of the couple talk about the 28-year-old's loyalty to John and her commitment to their marriage, described as "100 per cent solid".
There is also an exclusive interview with former WAG Suzie Walker, who is friendly with both Toni and Vanessa.
Suzie, who was married to former England goal keeper Ian Walker for 13 years, got to know Toni well in 2004 and recalls how much, even then, the pretty blonde "doted" on John.
"She loves him so much and he is the father of her children," Suzi says. "Toni always wanted children and will make the effort for the marriage to work because of them. It's not the only reason but it's an important one."
She also reveals how she recently met up for coffee with Vanessa, whom she says is shocked by the backlash she has encountered since the alleged four-month affair was revealed.
