The music mogul - who has two-year-old son Eric with partner Lauren Silverman - enjoyed some cheeky banter with Faye Horne as she auditioned for him and the other judges, Louis Walsh, Nicole Scherzinger and Sharon Osbourne.

When Faye, 24, introduced herself, Simon, 56, quipped: "I thought you said you're horny."

Faye told him to "behave" and Simon replied: "I haven't done anything, Faye."

Sharon then encouraged Simon to turn around and face the wall so he wouldn't distract the blonde beauty from her performance of Sam Smith's 'Writing's On The Wall'.

She said: "Just turn around because she is going to keeping laughing if you're looking at her. Just do it to give her a chance to sing."

And after an ecstatic Faye received four yes votes, she told Simon she loved him and asked: "Is the feeling mutual? you know it is."

Simon jokingly replied: "You're trouble with a capital T."

Meanwhile, on Saturday's (10.09.16) show, a pair of 'X Factor' hopefuls got engaged in front of the judging panel.

He Knows She Knows singer Stephen went down on one knee to propose to his partner Sharna after they impressed the judges with a rendition of Justin Bieber's hit track 'Love Yourself'.

Following their performance, Stephen said: "Can I just stop for one second? Before we go, I'd like the opportunity to ask this beautiful woman if she will be my wife?"

He turned to Sharna and said: "Will you marry me?"

The proposal left the whole room in tears. When Sharna said yes, Simon excitedly called the couple over to examine the ring.

He said: "I want to see the ring. Oh my gosh, your hands are shaking - come here. Your ring is beautiful!"

Sharna and Stephen have enjoyed a whirlwind romance, having only met six months ago. They moved in with each other two days after their first meeting and their audition was the first time their parents had met.
