They sit alongside each other every Saturday night on The Voice and now Will.i.am wants to bring their friendship into the recording studio.
The Black Eyed Peas hit maker is so convinced of Jessie J’s global appeal that he is desperate for them to collaborate on a track together.
And it’s not only Jessie vocal ability that has impressed the rapper, he also adores her feisty personality and believes she would go down a storm in the US music charts.
He said: “Meeting Jessie has inspired me to really go, 'Wow!' Because, she's like that. She's bubbly, she's crazy. She's like raw, edgy. I would love to make her a star in the U.S. She's really fresh... she's dope."
