Lily Allen Back With Ex Ed Simons?

Lily Allen has fueled speculation she's back together with her ex-boyfriend Ed Simons after changing the status on her Facebook page.

The 'Smile' singer and the Chemical Brothers star sent updates to their pals on the social networking site showing that they are "in a relationship" with each other.

Rumors that the couple -- who split earlier this year shortly after Lily suffered a miscarriage -- had rekindled their romance were rife after the pair were spotted getting cozy with each other at the UK's Glastonbury festival earlier this month.

Lily, 23, recently dismissed reports she was back together with Ed -- insisting she has maintained a friendly relationship with her former lover.

She wrote on her MySpace page, "I am not some failed baby making machine desperately to trying to win my man back. Sometimes I think these journalists are still living in the 1950s. No one knows anything about my relationships. Ed and I are friends, who went for lunch yesterday, that's it."
