John Mayer was seen "sneaking" out of ex-girlfriend Jennifer Aniston's house early on Wednesday morning.

The pair - who sparked rumors they had rekindled their romance after they were spotted passionately kissing earlier this month - enjoyed a romantic dinner at Los Angeles' Sunset Tower Hotel on Tuesday night, but went to great lengths to ensure they weren't pictured together.

Courteney Cox was "miserable" after having Botox injections. The former "Friends" star - who has a four-year-old daughter Coco with husband David Arquette - insists she wouldn't have the cosmetic procedure again.

Courteney, 44, said: "Botox? I think it's fantastic and also horrible. I mean, they've come up with this stuff that can make you not look angry. But you have to use it sparingly."

John Mayer insists his love for Jennifer Aniston comes "from the heart."

The singer - who began dating the former 'Friends' beauty in April - refused to elaborate on his romance with Jennifer but did say it was genuine.
