The rapper is due to play four UK dates this summer, including a headlining performance at the Wireless festival in London this June.

Jay-Z said he had talked to Allen about the possibility of joining him when they met at the BRIT Awards earlier this week.

"I spoke to Lily Allen. I'm trying to get her for Wireless," he told BBC Newsbeat.

"Hopefully that goes through. I bum-rushed them in the corner where they can't say no."

The rapper added: "I think she's a great artist I respect her. We just haven't [collaborated] yet."

Allen recently announced plans to take a break from music in order to setup her own record label.

Tickets for Jay-Z's UK dates – which also include shows in Manchester and Birmingham – are on sale now.
