The music boss stunned the X Factor USA audience with his best Elvis impersonation by belting out a line from ‘Can't Help Falling In Love.’
Simon accepted the challenge from his fellow judges Kelly Rowland, Demi Lovato and Paulina Rubio after Paula told X Factor hopeful Russ Pouliot that if he had a British accent he would sound like Simon when he sings.
I might actually end up signing myself
‘I feel like had you had a British accent you would sound like what Simon sounds like when he sings,’ she said.
When Simon said he didn’t know what Paula was talking about, Demi suggested: ‘Well why don't we listen to you sing?’
Kelly then joined in, adding: ‘Can you give us a sample?’
The former Destiny's Child star then jumped on stage to grab the mic from Russ as the music began playing again.
Although he initially made the excuse of a sore throat, Simon finally gave in and let out a line of the hit in the same wobbly style as Russ had.
Kelly told him: ‘I'm so proud of you. You did so good.’
While Simon joked: ‘I might actually end up signing myself.’
A shot of a Simon Cowell album then appeared on screen, as a voiceover announced: ‘Coming soon Simon Cowell's Greatest Hits available wherever fine music is sold.'
