Aniston still sweet for Mayer?

Jennifer Aniston - who split from singer John Mayer in April - is reportedly struggling to get over her old flame and has good luck messages delivered to the 'Gravity' star's dressing room before he performs.

A source said: "Jennifer sent John a hand-delivered perfumed note before one of his concerts recently.

"It read: 'Play well, you always do'. It was sweet. Clearly she doesn't want to let go completely."

Friends of the 30-year-old singer claim Aniston - who was recently romantically linked to her 'He's Just Not That Into You' co-star Bradley Cooper - has stayed in touch with Mayer's brother and a reunion could be possible.

The source added to Britain's Daily Express newspaper: "John hasn't shown any interest in other women since the split, which is a break from the usual pattern.

"Who knows, this may not be the end of their romance. Neither seems very good at letting go."
