There have been rumors that Jennifer Aniston is pregnant because of her weight gain, which made it appear that she has a baby bump. She explained the reason behind that during an interview with Look magazine, ''For the last year and a half I went from being a crazy workout girl to sort of saying, 'My body wants a little break.'"

The 45-year old actress added, ''The only downside to that of course is that there's that couple of extra pounds and 4,000 pregnancy rumors too, but you know, other than that, it all feels great." Jen may not be pregnant yet, but she definitely has babies on her mind.

According to new reports, the star of "Horrible Bosses 2" is currently getting fertility treatments so she can have babies. That's right...Jennifer Aniston may be pregnant soon and she's aiming to have twins! A source told National Enquirer (via Showbiz Spy), "Jen's always dreamed of having kids close in age, and while one baby would be great, she thinks twins would be an incredible blessing!"

The insider also revealed, "Jen knows that by having in vitro fertilization, she's much more likely to have twins, and she'd love that more than anything." Having a baby is not that easy. What more if you are having twins? This could mean less time for work and more time for the babies. Is she ready to take on the challenge?

A source close to the actress said, "Things haven't been easy for Jen and Justin, but they've stayed the course and bonded over their shared desire to start a family." The insider added, "Jen's excited to take on the challenge of having a child ... or children!"

According to the source, Jennifer Aniston even encouraged other women to get pregnant in their 40s these days. The insider said, "Jen's ready to be a mom. She's not fazed at all." I wonder how the former "Friends" star would feel once she finds out about the latest pregnancy rumors.
