Ahead of this, Phillip said he wrote the first line of his book in his head aged 14.
In 2017, he went on to pen the first chapter, but couldn’t finish it because the time wasn’t right.
Earlier this year, Phillip came out as gay on Instagram and This Morning after 27 years of marriage to his wife Stephanie Lowe.
The married couple share two daughters together; Ruby and Molly.
In a statement, he told fans he is “coming to terms” with being gay and said his feelings had been “consuming” him for the last few years.
