Jennifer Aniston 'Desperate' To Be A Mother And 'Has Been Trying To Conceive For A Year'

Jennifer Aniston has been the subject of more baby rumours this week, but it's now emerged that the Hollywood star is growing increasingly irritated by the constant speculation as she has apparently been trying to fall pregnant for the last year.

The Mail Online reports that the We're The Millers star and her fiance Justin Theroux have been trying to conceive since they got engaged in 2012, with Jen even keeping her work schedule to a minimum over the last few months to increase her chances.

An insider revealed to the website that while Jen is trying to remain positive, the constant intrusion into her life is starting to wear thin. "It's starting to be a source of irritation for Jen," a source said.

"Jen purposely left her work slate clean for the next few months to prepare for motherhood.  She puts a brave face on the rumours, but it masks her desperate desire to be a mother."

The 44-year-old actress was forced to denied yet more rumours that she is pregnant after it was alleged earlier this week that she was "thrilled beyond belief" to have fallen pregnant and would be keeping the news a secret until she was at least six months along.

Postponing her wedding to Justin has also caused plenty of speculation itself, with insiders recently admitting that they were unsure whether the two would ever wed.

A source previously admitted: "Jen's completely understanding of Justin's opportunity to elevate his career to another level and prepared to wait though friends are starting to question whether they'll never make it down the aisle!"
