Recent pictures of Jennifer Aniston sparked new rumors that she is pregnant.

The rumors swelled with pictures reported by TMZ that reportedly show the 43-year-old former "Friends" star with a baby bump.

The pictures were taken while Aniston was checking herself into a spa over the weekend in Beverley Hills, CA.

Aniston arrived for a day of relaxation on Saturday make-up free in a very casual style in grey sweatpants and matching top.

Gossip sites have noted that the actress's usually slim figure looks slightly fuller than usual within the past few weeks.

While the pictures are up for interpretation, the rumors began before any alleged baby bump was seen. The Daily Mail reported that Aniston has previously denied reports that she is carrying her first child with soon to be husband Justin Theroux.

The Mail also reported that Aniston has backed out of projects such as the film adaptation of "Getting Rid of Matthew" by Jane Fallon. This has caused speculation that she may be expecting a child some time next year.

Aniston has also reportedly declined offers of fish and alcohol during recent gatherings, according to The Sun.

The actress recently held a party this month at her home in Beverly Hills that was attended by big names including Demi Moore and Ellen DeGeneres. A source that attended the event told the women's magazine Grazia, "They had a margarita bar, but she didn't go near it, opting for water instead."

It is recommended that pregnant women do not eat fish and Aniston showed a new tendency toward shying away from particular foods.

"It was so unlike her and didn't go unnoticed," the Grazia source said about Aniston's eating habits. "She was also picky with what she ate, and didn't touch the huge sushi platter, which is one of her favorite foods."
