John Mayer is not over Jennifer Aniston, claims his ex-lover. The "Gravity" singer is reportedly "pining" over the actress - who he split from in March after around a year together - revealed Scheana Marie Jancan, who dated the star briefly last month.

She told Britain's Heat magazine: "John was devastated at the break-up with Jennifer. He told me he really didn't think Jennifer would dump him - it was a complete shock to him."

Jennifer Aniston says actor Steve Zahn is her "absolute love." The actress - who has been single since splitting from musician John Mayer in March - loved teaming up with her old friend for new movie "Management."

She said: "He's the best, my favorite. He's my absolute love. I've known him for so many years."

John Mayer has ended his new romance - because his girlfriend was too open about their relationship. The musician - who has regularly written about his personal life on his internet blog - was reportedly furious with aspiring actress Scheana Marie Jancan for talking about him and is now refusing to speak to her.

According to pals of 24-year-old Scheana, she is "nervous" that she hasn't heard from the singer since she opened up to tell an online magazine about him last week.

Taylor Swift stalks her ex-boyfriends. The "Love Story" singer - who has previously dated Joe Jonas of the Jonas Brothers - likes to spy on her previous partners as she wants to know what they're doing.

She is quoted as saying: "In my spare time I like to drive past my ex-boyfriends' houses. I'm not like throwing eggs - I just like to check up on them. Everybody does that - it's just that nobody admits to it!"

Jessica Simpson reportedly enjoyed an intimate lunch with ex-boyfriend John Mayer. The singer-and-actress, who is currently dating American football star Tony Romo, secretly met John for a meal in Calabasas, California, recently and onlookers claimed they couldn't contain their joy at seeing each other.

One source told X17Online: "They were keen not to be seen together but they looked so happy to be in each other's company. It looked to me like they were more than just good friends!"

John Mayer has stopped smoking marijuana. The "Gravity" singer - famed for his wild and womanizing ways - no longer indulges in the drug and jokes he hires someone to replicate users' perceived benefits of the substance.

He wrote on his Twitter account: "Any time I feel like smoking pot I just book myself a life insurance exam."
