Watch: Matt Willis admits using six grammes of cocaine a day
The 40-year-old musician and TV presenter — who has three children with wife Emma Willis, 47 — has opened up about his drink and drug addiction battles in a new BBC documentary due to air on Wednesday 17 May.
Matt revealed he was offered the Class A drug after a concert in 2016, having previously been to rehab several times for alcohol addiction.
He said: "I was like, 'Cocaine wasn’t a problem for me, alcohol was my downfall'
"Within a month I was doing six grammes, bang, bang, bang, bang, on my own every f***ing day and not coming home until 3am in the morning, pretending I was working on my album.
"I wasn’t really writing I was making s*** music in the studio doing coke.
"It was straight back to that shame cycle, the shame of relapse, the same of letting everyone down, the shame of using uncontrollably trying to stop and not being able to."
Emma — mother to daughter Isabelle, 13, son Ace, 11, and seven-year-old daughter Trixie with Matt — admitted she failed to spot the signs on her husband's relapse.
She said: "I didn’t expect it. I think because he had been doing so well for such a long time.
"It was the last thing I thought."
Matt has said he was "conniving and manipulative" in hiding his addiction.
He told the Radio Times: "Addicts are very good at hiding everything. I’m yet to meet a stupid addict. They’re conniving and manipulative."
The couple married in 2008 with Matt having attended rehab ahead of the wedding. They renewed their vows in 2018.
