Jennifer Aniston and John Mayer have been getting creative by declaring their feelings through the medium of song and poetry.

The former Friends star is said to have written a lengthy poem for her beau which he then transformed into song to serenade her with.

"He changed it poem a little bit to make it more lyrical," an insider told Star.

"But it's all John Mayer style, so it sounds good.

"She said, 'It was only a little something I wrote down for you, and you made it beautiful.' And then she joked, 'Do I get the publishing rights?' "

Ironically John is said to have twisted the lyrics to highlight their controversial break-up.

The lyrics read: "Lucky in love, lucky in love, didn't forget me when I asked you to leave me."

"Didn't forget me/ Now you're alongside me/ You've brought luck to love/ I've been hit by a truck in love."
