Jennifer Aniston Pregnant? Actress Wears Oversized Coat, Avoids Alcohol

Jennifer Aniston has fueled pregnancy speculation just one month after her representative denied that she is expecting a baby girl, as new reports claim that the actress is avoiding alcohol and clearing her work schedule.

The former "Friends" star recently stepped out in Los Angeles with her fiancé Justin Theroux and her appearance did little to dispel the pregnancy claims. Aniston, 43, was dressed in an oversized coat, which immediately raised questions about a possible baby bump, according to Grazia magazine.

One source claims that the actress steered clear of alcohol and raw fish during her recent engagement party, which some critics perceive to be a sign that she and Theroux are expecting their first child.

"They had a margarita bar, but she didn't go near it, opting for water instead. It was so unlike her and didn't go unnoticed," a source told Grazia about the event, which was attended by close friends Demi Moore and Ellen DeGeneres.

"She was also picky with what she ate, and didn't touch the huge sushi platter, which is one of her favorite foods," the source added.

Aniston has allegedly begun clearing up her work schedule for 2013, which fans suspect may be in preparation of a baby. The Daily claims that the actress pulled out of "Getting Rid Of Matthew," a film adaptation of the book by Ricky Gervais' partner Jane Fallon.

The pregnancy rumors follow reports that the couple, who announced their engagement in August, is planning to wed in February 2013 on Valentine's Day. They are also said to be finalizing their wedding guest list.

"Jen and Justin are super anxious to tie the knot, but they looked at their schedules and decided this coming February 14 is reasonable to shoot for," a source told OK! Magazine.

"Jen just wants to make sure they get married before Justin starts filming Swear to God," the source added, referencing Theroux's upcoming project.
