Los Angeles - James Corden says Kanye West has pulled out of doing Carpool Karaoke twice.
The Late Late Show host is determined to get the Famous hitmaker to appear on the popular segment on his US late night television show and says the 38-year-old rapper is keen to make it happen "eventually".
In an interview with Britain's GQ magazine, he said: "Kanye has been booked to do it twice now but both times something came up.
"He'll do it eventually... He wants to do it."
Meanwhile, the 37-year-old comedian has set his sights on having R&B superstar Beyonc? join him in the car to perform some of her biggest hits.
He said: "It would break the internet. She's on tour right now. We're working on it."
Justin Bieber, Coldplay, One Direction, Adele, Stevie Wonder and One Direction have all had their turn.
And James previously admitted doing Carpool Karaoke with Sir Elton John was worth "hundreds of thousands of dollars".
He said: "We did Crocodile Rock, and it's flamboyant.
"To sing Tiny Dancer with Elton John in a car, you just think: 'If this was an auction prize, it would go for hundreds of thousands of dollars.' I feel lucky every time I get in the car with any of these people who I just really admire and respect."
And the British funnyman thinks his carpool guests have an equally nice time belting out their back catalogues.
Discussing Chris Martin's recent appearance, he said: "After every song he was like, 'Oh, I haven't heard that for ages!' Or, 'It brings me back to where I wrote this!'
"It's actually quite a lovely thing for them to reminisce; they hear their whole career in eight songs."
