Phil Collins is set to be quizzed under oath following allegations that he did not 'wash or brush his teeth for months'.
The 70-year-old drummer will sit down for a recorded deposition as part of an on-going legal dispute with his ex wife, Orianne Bates.
The clash revolves around the their mansion in Florida, of which his former spouse claims she was verbally promised half.
The Genesis singer will face a number of questions from Bates' lawyers focusing on a number of allegations she has made in the past.
This includes claims that he did not brush his teeth for months, stopped showering, and abused alcohol and prescription medicine.
She also says he became 'depressed, abusive and incapable of having sex', according to the Metro.
The questioning is set to take place in December after Collins' current tour.
Importance of tooth brushing
Current NHS guidance recommends that we should brush our teeth twice a day for around two minutes to help maintain oral health.
It should happen last thing at night and on one other occasion during the day.
Adults should use a toothpaste that contains a minimum of 1,350 parts per million (ppm) fluoride.
All surfaces of the teeth should be brushed including the inside, outside and chewing surfaces.
