Singer John Mayer desperately wants Jennifer Aniston back

London: Now-a-days, the "Gravity" singer John Mayer is shedding tears and desperately needs her ex-girlfriend Jennifer Aniston back.

According to contact music, the sobbing singer reportedly telephoned his ex-girlfriend and begging her to take him back in her life. John Mayer dumped the Hollywood actress in March month this year.

A source has revealed: "John asked Jen if they could go back to seeing each other exclusively. The call came as a massive surprise and of course Jen is delighted with John's announcement - who wouldn't be?"

The 31-year-old singer has reportedly promised her to give his best shot, if she gives him a chance to get back in her life.

The source has also explained to Britain's Look magazine: "John suggested that if all is going well with them in six months, then they can begin discussing marriage and building a life together. Jen was floored! John always seemed so anti-commitment before. But now he's begging Jen for another chance and he's promising to give the relationship his best shot."

Source has also added: "Despite his big plans, John suggested they don't rush into moving in together. She'll keep her house in Beverly Hills, while John will continue to live in Pacific Palisades. I think it's just because he wants to move slowly and avoid mistakes they made previously."

On the other hand, the damsel is busy with her most recently linked Gerard Butler, with whom she stars alongside in two forthcoming segments: The Bounty and Bradley Cooper.
