will.i.am wants to work with Madonna.
The Black Eyed Peas star - who has previously collaborated with the likes of Britney Spears and Justin Bieber - thinks the 'Ray of Light' hitmaker is "the queen" and though he's got the means to contact her, he won't broach the subject of a collaboration until he sees her face-to-face.
He said: "I'd love to work with Madonna. It's like, Madonna! The queen!
"I've got her number so I could WhatsApp her but things like that you're supposed to do right in front of their face.
"I don't want to go through a phone and let some other company have my conversation. I'd want to do it in person."
These days, the 44-year-old star and his Black Eyed Peas bandmates, Taboo and Apl.de.ap, lead quiet lives and things don't get too raucous backstage at their gigs.
Taboo told Closer magazine: "None us drink so there won't be champagne. There'll probably be tea, I really like tea."
will added: "There'll be some nice vegan food, because I'm vegan.
"Probably fruits, vegetable platters and salads.
"I really like ginger too so I hope there's some of that. We can have fun without alcohol."
will recently admitted he is keen to work with Cheryl - who he managed until 2013 - again in the future and they have been discussing the possibility of a collaboration.
He said: "We talked about it at a Post Malone concert.
"I would love to work with Cheryl again, she is awesome."
