Lily Allen has delayed her exit from the music world yet again, confirming an appearance at Wireless Festival this summer.

The singer is playing the London festival at the personal request of the Sunday headliner Jay-Z.

She enthused: “I was very flattered to hear that Jay-Z wanted me to support him at Wireless and, combined with my dates in March with Dizzee Rascal, I am excited to end my current string of live shows in such prestigious company.”

Also joining Jay-Z on the July 4th bill is Mr Hudson, with more names to be confirmed.

The Friday sees Pink, The Ting Tings, Gossip and The Temper Trap share the bill, while it's widely predicted that Eminem will be heading Saturday.
