The musician - real name Paul Arthurs - added that he would be taking a break from performing with former Oasis frontman Liam Gallagher.

Bonehead was a founding member of Oasis and typically played rhythm guitar in the band, which became one of the biggest groups Britain has ever produced.
He left the band in 1999, 10 years before the exit of chief songwriter Noel Gallagher, which saw Oasis break up for good.
Noel walked away after his sibling rivalry with Liam reached breaking point, and the brothers still haven't reconciled almost 13 years on.
Noel has since achieved solo success as Noel Gallagher's High Flying Birds, while Liam's band Beady Eye released two albums before breaking up.
However, LG subsequently followed in his brother's footsteps and went solo, headlining festivals and releasing two albums that have topped the charts.
In recent years, Bonehead has been reunited on stage with Liam, performing as part of his band.
The pair were due to take to the stage together at Knebworth once again this summer, 26 years on from Oasis' historic gigs, which were the subject of a documentary released last year.
