This week’s cover of the National Enquirer reads “Jennifer Aniston’s Pregnancy Secret” and features an older picture of Aniston on set several months ago with a questionable mini-bump, but there are pictures of Aniston out with Courteney Cox on Christmas Eve and she definitely looks pregnant! Jen is shown wearing black leggings and a loose black top while clutching a scarf close to her face. There’s been a lot of speculation that Aniston got another nosejob, possibly her third, and that could be why she’s trying to cover her face, but her face also looks fuller and she’s gained weight all over. I would bet that she is indeed pregnant.

Aniston has also been lying low apart from this public outing with Courteney and hasn’t been photographed over the past few months – and a pregnancy could explain her absence.

Star Magazine reported this week that she’s been living with Sex and The City heartthrob Jason Lewis, and also that Lewis was flying his mother in to meet her over the holidays. Could it be because she’s pregnant with his baby? That’s going to be one gorgeous child.

Here are excerpts from Star’s article about these two. They claim they’ve only been dating since November, so Aniston got knocked up in record time if it’s Lewis’ baby. I’ll report on the Enquirer story after I get access to it over the weekend:

“Jason’s mother, Nancy, is flying in from Missouri just to meet Jennifer,” says the insider. “It’s really important to him.” And that’s not all! “He’s so thrilled because he’ll also get to introduce Jennifer to his sister Nicole’s new baby girl, Makela. It’s going to be a very warm and cozy holiday at his grandmother’s house in L.A>, and everyone is thrilled to meet the woman Jason has been raving about!”

Ironically, Jason has ties to Brad Pitt. The two are acquaintances, and Brad even introduced Jennifer to Jason, 36, while they were still married! They eventually reconnected in November, after they’d both become single, and there was instant chemistry.

“Mutual friends at the St. Jude Children’s Research Hospital charity thought Jen and Jason would make a great couple,” the insider explains. “So they started e-mailing. After their first date, they began seeing each other every day, nonstop.”

Now they’re virtually living together – they spend all their time at her Malibu house or his place.

The article goes on to say that their relationship progressed so quickly because they have a lot in common. Both Aniston and Lewis like to work out, and are homebodies who would rather stay home than go out. Now that they’re expecting a baby they’re going to have an even more compelling reason to stay home. I bet you it’s true, but hopefully they’ve been dating more than just a month and a half if Jennifer is so pregnant she’s already showing.

Update: Aniston’s rep has denied reports that she’s pregnant, but so did J.Lo’s rep at the beginning too.
