The music mogul is clearly unimpressed with Dermot - who hosted the show for eight years until his departure last year - for making several digs at ‘X Factor’ while he hosted the NTAs earlier this week, including when he joked: “Yep, I’ve still got this job… for now.”
Speaking to the Sunday People, Simon said: “He’s got the NTA job – yeah, for once a year. That’s a big move.”
He also suggested Dermot might already be wishing he could backtrack over the comments, which included suggesting that ‘Strictly Come Dancing’ was his “new favourite show”.
“He’d be fantastic on 'Strictly'. I couldn’t care less if he goes on it.”
Earlier this month, Dermot offered his suggestions to breathe some new life into ‘The X Factor’, after the last series was met with a lukewarm reception from fans and critics, as well as notably low viewing figures.
In addition to the NTAs and his BBC Radio 2 show, Dermot is currently hosting ‘The Getaway Car’ on the BBC, and stepped in to host ‘Children In Need’ back in November, when regular host Terry Wogan had to pull out due to illness.
