Jennifer Aniston's Rep Denies John Mayer Marriage Reports

Jennifer Aniston's rep is speaking out against reports the actress is set to wed beau John Mayer.

America's OK! claims in its latest issue that the former 'Friends' star, 39, is planning a low-key wedding with crooner Mayer this fall. They also reported that Aniston will wear a Vera Wang dress to the ceremony; there will orchids everywhere; and they will serve champagne and caviar. "She's at an age where she is thinking with her head not just her heart," the mag quotes a source as saying.

But Aniston's rep insists, "She is not getting married."

The rep also spoke out to deny reports in Star magazine suggesting that Aniston in going to have Mayer's baby "as Brad and Angie's twins wow the world."

"Both headlines are complete fabrications," Aniston's rep tells US Weekly magazine.
