Simon Cowell couldn't hide his blushing face after Dermot O'Leary shared a hilarious throwback photo of the music mogul during The X Factor on Saturday night.
As the singing competition was enjoying 'disco week', the show's presenter revealed Simon's own groovy look from back in the day by sharing a photo of the 57-year-old jokily flexing his muscles and posing for the camera in a vest top and braces with long Seventies-style hair while Sinitta smiles next to him.

While his co-judges burst into laughter over the old school snap, Simon went red with embarrassment, joking: "By the way, that was not me!"
Dermot then compared the judge to the show's most controversial contestant, Honey G, saying "Looking a little Honey G there aren't we?" before telling the crowd "I say Simon, you say Cowell!"
Dermot then joked that they should probably stop teasing him, saying: "He's probably about to sack me again," referring to his brief departure from the show last year.
The presenter has previously opened up about briefly leaving the show.

"I don't have a God-given right to that job," Dermot explained. "But I always said, 'If I find out they are talking to anyone else, I'm not going to play games, I'll just go'.
"So I called my wife and woke her up to tell her I was leaving The X Factor - which was a shock, as you can imagine…I called ITV and actually didn't speak to Simon. I texted Simon and got a lovely text back but at the time I wanted to keep that at arm's length."
Dermot admitted that Simon called him up to invite him back, revealing that he had said: "I've back a mistake, I'd love to get you back.
"Actually I think we're closer now than we ever have been. We text all the time."
