Allen pens song about Corden romance?

Lily Allen has reportedly written a new song about her supposed romance with Gavin & Stacey star James Corden.

According to the Daily Star, Allen has penned a tune called 'From Barry To Billericay' in honour of the comedian.

She allegedly sent the track's lyrics to the TV star in an envelope. One line from the song reads: "Your heart is the ocean we all get swept in."

Allen posted two new tunes on her MySpace last week that she claimed demonstrated her "new direction".

Corden recently played down rumours of a romance with the singer, insisting that they were just good friends.
