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."

Silvar proposes to Sharna

Producing a ring, the 28-year-old asked Sharna, 25: "Will you marry me?"

After she nodded yes, Simon said: "I want to see the ring. Oh my god, your hand's shaking - come here."

Simon gave Sharna a hug

The music mogul gave her a hug and told her to "go and celebrate", while Sharon admired the ring: "That is beautiful."

Speaking after leaving the audition room, Sharna said: "I don't think I've had a happier day in my life."
