The two had been dating for six months, with Silvar explaining: "It is like a fairytale, true love."

Having auditioned under the stage name He Knows She Knows, Silvar asked: "Can I just stop for one second?"

In front of judges Simon Cowell, Nicole Scherzinger, Louis Walsh and Sharon Osbourne, he said: "Before we go I'd like the opportunity to ask this beautiful woman if you will be my wife."
