Lily Allen to play at Wireless Festival with Jay-Z

Lily Allen is performing with Dizzee Rascal at London's O2 in March

Lily Allen has confirmed she'll be appearing on the same line-up as Jay-Z at the Wireless Festival in July.

The rap star said that he wanted to sing with Lily Allen after hearing her perform at last week's Brit Awards.

The Smile singer had previously said she'd be taking a career break after her concert at London's O2 Arena with Dizzee Rascal in March.

The Wireless festival takes place in London's Hyde Park between Friday 2 July and Sunday 4 July.

It'll also see performances from Pink, The Temper Trap, Gossip, The Ting Tings and Mr Hudson.

The news of Lily Allen's appearance is a turnaround for the singer, who told Radio 1's Sara Cox in December that she wanted to take time off.

She said she wanted to start her own record label, set up a fashion shop with her sister and spend more time at home.

Lily Allen won the best British female award at this year's Brits and also sang her single The Fear.

At the awards, Jay-Z admitted he was keen to be on the same stage as her.

Jay-Z said: "I spoke to Lily Allen. I'm trying to get her for Wireless. Hopefully that goes through.

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

"I know her for a minute," he added. "I think she's a great artist I respect her. We just haven't [collaborated] yet."

Ahead of Wireless, Jay-Z will play Manchester's MEN Arena on Monday 7 June and the LG Arena in Birmingham on Wednesday 9 June.

He's also headlining the Isle of Wight Festival on Friday 11 June.
