But eight years later, a marriage and two children later, Pete and Emily are stronger than ever.
Today marks their fifth wedding anniversary, after having tied a knot at a beautiful Devon ceremony in 2015.
They remain as in love as ever, and although they boast of a “balance” for their family, the couple is not afraid of one or two disagreements.
In fact, Pete says it’s a vital lesson to learn.
“We have two completely different ways of looking at it,” said the 47-year-old to the Sun, “but we are creating a great balance. ”
The couple recently decided to send their children back to school – even though Peter initially objected.
But Emily had said it would be a good thing, and, trusting his expertise as a doctor, Pete came to accept it.
Emily once said that she didn’t want their children’s faces to be shown – something Peter didn’t do for his other children.
They share Millie, six, and Theo, three, while Peter has Junior, 15, and Princess, 13, with ex-wife Katie Price.
While Junior and Princess have been in the spotlight since they were just toddlers, Emily insists that Millie and Theo be kept out of the cameras – which Pete seriously respects.
Emily added that when Junior and Princess were little, social media was not such a serious force.
But nowadays, she says, it’s a different story, and she doesn’t let her children be exposed to it.
“Millie once asked me why her face couldn’t be shown on TV, but I think 100% it’s the right thing to do,” said the beloved mom.
She continued, “I have seen comments where people are horrible about the appearance of a famous baby and children. “
