The couple had the boy in May 2014 while they were in rock band Comanechi.

Filming the drama in Los Angeles means Charlie rarely sees his son, who lives with his mum, also 23, in London.

A source said: “Charlie became a dad when he was just 20. He met Akiko when he was just a teen and fell head over heels in love.

“They’re no longer together but they have an amicable relationship for the boy’s sake.
