Jennifer Aniston dumped John Mayer over desire for a baby?

Jennifer Aniston’s desire to have a baby reportedly played a part in her break-up from John Mayer.

The former Friends is said to have dumped on-off boyfriend of a year John earlier this month after he grew “cold”.

A source told OK magazine: “John wasn’t ready to father her child so she ended it.”

The source explained that while Jennifer puts a lot of her focus into her relationships: “John’s number one priority is his music. Which is all-consuming for him.”

But as with their split last summer - which saw them reconciled just three months later, the source added that the pair have a never-say-never attitude to getting back together again once John’s next album is out of the way: “They left the door open to give it another go.”
