Jennifer Aniston's camp refuse new reports she is pregnant at 44 with Justin Theroux's child

Over the years there have been dozens of reports that Jennifer Aniston has been pregnant, all false.

On Wednesday UsWeekly made that claim again with the excited cover line, Jen's Big Secret, Pregnant!

But the actress' rep strongly denies the story, telling MailOnline, 'Jennifer is not pregnant.'

The publication printed a rep denial, but still proceeded to detail how the Friends star, 44, has been trying very hard to hide the fact that she is expecting a child with her fiance Justin Theroux, 42.

'She's thrilled!' a source tells the weekly magazine. 

The source adds that the couple, that fell in love on the set of Wanderlust, is 'extremely happy' and this 'is the baby Jen always wanted,' adding the child is due in 2014.

Us Weekly claims the Emmy winner has been struggling to hide her 'growing bump' as she promotes her two films We're The Millers and Life Of Crime.

The magazine also reports the actress has had to rethink her wardrobe after wearing a tight-fitting purple satin Burberry dress at the New York We're The Millers premiere on August 1.

'Her stylist had to redo her whole press tour wardrobe,' a source tells the publication.

Instead of asking designers to borrow outfits in bigger sizes to accomodate the star's expanding waistline (which would alert several people that the beauty was gaining weight), the stylist had to go to clothing stores and buy new dresses by Alexander McQueen and Chanel straight of the rack, the article details.

Though Jennifer did not look pregnant at the September 15 Toronto Film Festival premiere of her new film Life Of Crime, the article claims she relied on a Vivienne Westwood gown that had a corset inside and layers of fabric over the stomach on the outside to hide her baby bump.
