The new father has become the latest celebrity to speak out on Scotland’s future in the run-up to the independence referendum in September.
Cowell was reported to have said he has “Scottish blood” and wants the UK to “all be together”.
Meanwhile, Scots actress Rose Leslie, who stars in Downton Abbey and Game of Thrones, said she had a “real concern about independence”. Cowell, who is to return as a judge on X Factor later this year, reportedly said: “My mum’s maiden name was Dalglish so I have Scottish blood in me. Personally, I would like us all to be together.
“At the end of the day, it is their decision, obviously. But I would prefer us to remain one big happy family.”
Leslie said: “First and foremost, Scotland is my home and I do consider myself Scottish, but I also feel very British and I hope that Scotland stays within the Union. I have a real concern about independence.”
