Emma Willis sobbed as she revealed the journal in which her husband Matt Willis kept track of his drug and alcohol use.
In a new BBC documentary, the Busted icon, 40, discusses his battles with addiction and the impact it has had on his relationship with the former Big Brother presenter, 47.
While the artist has been clean for five years, he said that during his most recent relapse, which occurred during a Busted tour, he would use 6 grammes of coke alone every day.
Emma said that throughout the height of Matt’s drug and alcohol abuse, she kept a diary tracking exactly what he ingested, which she still retains in a drawer in their bedroom.
She told the Matt Willis: Fighting Addiction programme makers: ‘The only thing I couldn’t think of to keep track was to write a diary. I don’t think I’ve ever read it since I wrote it.
‘It’s literally just notes of what I knew he had consumed.’
Emma began reading some of the entries, in which she had documented Matt drinking whole bottles of champagne, wine and ‘more.’
She added that ‘and more’ was a reference to drugs.
Becoming tearful, she continued: ‘I mean it’s every single day. Without fail.’
Emma recalled: ‘I remember I used to drive around looking for him and go in all the local pubs looking for him but he went in the ones I didn’t know about.’
Matt previously admitted it wasn’t easy getting Emma involved in the documentary, telling Lorraine she ‘took some talking to.’
He continued: ‘We’ve been quite private with our lives, and not really opened up before. I felt like that was such a powerful part of it. She went through everything with me.’
Emma and Matt married in 2008 in Northamptonshire after three years of dating.
They have three children: Isabelle, who was born on June 20, 2009, Ace, who was born on November 26, 2011, and Trixie, who was born in May 2016.
