Lily Allen Back With Ed Simons?

Pop star Lily Allen has fueled speculation she's back together with ex-boyfriend Ed Simons after the pair were seen having lunch together earlier this week.

The former couple arrived at London celebrity hot-spot Nobu, meeting inside for an intimate catch up before eventually leaving via a side exit to avoid being snapped together by the awaiting paparazzi.

The pair were recently spotted together at Notting Hill restaurant E&O.

But the 'Smile' singer was quick to shoot down rumors of a reconciliation with the 37-year-old 'Chemical Brothers' star at the time.

In a blog post dated May 23, Lily wrote, "I went for lunch with my ex boyfriend yesterday, lunch.

"I am not some failed baby making machine desperately to trying to win my man back.

"No one knows anything about my relationships. Ed and I are friends, who went for lunch yesterday, that's it."
