As rumors swirl yet again that Jennifer Aniston is expecting her first child, the "We're the Millers" actress is weighing in with her thoughts on finally starting a family.

When asked if playing a fake mom in the new flick inspired her to become a mom in real life, or deterred her from the idea, Aniston admitted that it's a little bit of both.

"My friends are the ones who make me say 'heck no!'" she joked to E! News. "They get into trouble and they'll probably break your heart one day... just like boys. But that's okay. Nothing wrong with a good child messing with your mind."

The 44-year-old former "Friends" star, who is engaged to fellow actor Justin Theroux, has been the subject of countless pregnancy rumors over the years. The latest one started when she arrived at the "We're the Millers" premiere sporting a hip-hugging dress that revealed what looked to be the start of a small baby bump.

"She definitely seemed to have gained some weight," a source reportedly told In Touch magazine, adding fuel to the fire. "She knows the clock is ticking - she's well aware of it. She's also done her homework. She's explored all methods for having a baby and knows what her options are with IVF. She's educated herself."

Other reports have speculated that Aniston has already started in-vitro fertilization in hopes of becoming pregnant before she turns 45 this February.

While Aniston hasn't commented on the reports, she has opened up about starting a family with Theroux in the past, noting she thinks he would be an excellent father.

"I know Justin, for instance, has extremely amazing paternal instincts," she said. "Because [growing up] he had to sort of become the parent. I think when you have to become the parent when you're a younger person, you learn those instincts."
