How did Peter and Emily meet?
Peter and Emily met in 2010 when she was a medical student (she is now an NHS GP).
Emily's doctor father treated Peter after he suffered from a severe bout of kidney stones.
Peter thanked him by inviting him to his Plymouth concert. Here he was introduced to his daughter Emily - and the rest is history!
They went on to have two children, daughter Amelia, six, and son Theo, three.
Peter, who was married to Katie Price from 2005 to 2009, also has son Junior 15, and daughter Princess, 13 with the former glamour model.
He has continually spoken of how much he is in love with Emily.
The GP has been working throughout the coronavirus pandemic, and Pete has praised her noble efforts.
He even revealed that she secretly battled the virus herself.
Speaking to The Sun, he said: "Emily became ill when the cases were soaring. Nobody knew the symptoms, not all doctors wore masks and Emily was very exposed."
He added that although she has tested positive for antibodies, this doesn't guarantee that she is now immune to COVID-19.
"Just because she’s had it doesn’t mean she’s immune. Is she even more likely to get it again?"
