Sources claim that Jennifer Aniston is pregnant with John Mayer's child.

Australia's New Weekly alleges that the pair's recent rekindled romance began when Aniston realised she was expecting her first baby.

"The pair made their first outings as a reunited couple last week, enjoying a romantic weekend in New York and a concert in Boston," says the magazine.

"But while friends are scratching their heads about what made Jen take the playboy musician back, the smile the actress has been wearing says it all - she's pregnant and loving it!"
