The pair have teamed up for 'Fall In Love', which will be included on the British singer's debut album ORA.
"That's a great song… that's a fall in love, 'I don't want a one-night stand, I want to be in love with you' kind of song," Ora told Capital FM about the track.
"will.i.am and I went into the studio and we just completely got in the zone and recorded it and it just came out great… I'm just so happy it's on the album."
She added: "He is a cool guy and he's well fun, and he's so smart, he's a very smart man."
Ora's debut album will be released in the UK on August 27.
Meanwhile, the star's latest single 'How We Do (Party)' is on course to become Ora's third number one in the UK.
