Robbie Williams has revealed that his father Peter has been diagnosed with Parkinson's disease.
The 46-year-old singer is currently isolating at his home in Los Angeles with wife Ayda Field and their four children.
Williams said he has been experiencing "fear and panic" while his 70-year-old father, a former singer and comedian, is in the UK.

He told the Mirror: "We've got a lot of family issues right now. My dad has got Parkinson's, my mother-in-law who I love dearly has got a very big illness. We can't get to them. My dad is thousands of miles away."
Williams added: "My mum is just a year short of 80 and she's in isolation and I can see the things whirling in her mind and her eyes going."
The X Factor judge, who has been open about his mental health struggles, said he has learned to deal with his problems in a healthier way.
He said: "I noticed at the start of the lockdown that I was going into fear. But the difference between me now and the person I used to be . . . I saw it, thought 'That's interesting - tomorrow will be different'. And it was."
Former Take That star Williams has often been joined on stage by Peter, including Robbie’s show at the Aviva stadium in Dublin in 2017.
