Kate Moss has the X-Factor! Supermodel is spotted serenading Simon Cowell in karaoke bar – could she now launch a singing career?

She has been one of the top performers in the modeling world for decades.

Now it looks like Kate Moss has proven to Simon Cowell that she also has the X-factor when it comes to singing – after she was spotted serenading him at a karaoke bar this weekend.

Speculation was rife today that the Britain’s Got Talent judge might be about to embark on a music career, after exclusive photos and videos obtained by the Mail show the supermodel dishing out a series of sing-along favorites to the mogul.

Kate is no stranger to singing in front of an audience, first singing professionally on Primal Scream’s 2002 cover of Some Velvet Morning and later providing vocals for ex-boyfriend Pete Doherty’s band Babyshambles, regularly appearing on stage when she were another couple.

She also performed at a number of charity gigs alongside Pink Floyd’s David Gilmour and legendary rock chick Chrissie Hynde.

Stunned onlookers did a double take as Cowell and Kate arrived at the Lucky Voice bar in Islington, London, on Saturday afternoon.

But a solo record deal has eluded her… maybe until now.

It wouldn’t be the first time Cowell has backed an unexpected new venture into showbiz: he was the mastermind behind actors Robson and Jerome’s smash hit Unchained Melody in 1995 and signed the Zig and Zag puppets for two singles the same year.

Stunned onlookers did a double take when Cowell and Kate arrived at the Lucky Voice bar in Islington, London, on Saturday afternoon, where the 50-year-old supermodel sang Gloria Gaynor’s I Will Survive, Madonna’s Papa Don’t Preach and Queen’s Don. Don’t stop me now.

Daryl Falopios, a regular at the bar, said: ‘It was incredible. Kate really got into it and danced around, despite Simon making some typically caustic comments.

When she sang Bros’ When Will I Be Famous, he joked: “You won’t.” ‘But later she did Wannabe by The Spice Girls and he seemed impressed. I heard him say to her, “Okay, let me stop you there. I really didn’t like that, I absolutely loved it!”.

It’s not the first time Cowell, 64, has tried to boost Kate’s singing career. After hearing her sing with ex Doherty in Dublin in 2006, he said: ‘I’d like to offer Kate Moss a record deal whether she can sing or not.

‘The thing about Kate is she’s a star – it’s the ‘Kate factor’. People attach themselves to her and immediately become interesting.’

Former record company boss Joe King told the Mail that a Kate Moss version of Simon and Garfunkel’s April Come She Will or The Who’s Won’t Get Fooled Again could storm the charts.

“As always, not everyone will buy it, but some will,” he said.
