Even with Jennifer Aniston's latest stunning fashion choices, rumors still persist that she is pregnant.

The "Friends" star slipped into a classic black leather dress by Dior for the People's Choice Awards on Jan. 5 and came out of the show with the honor of Favorite Comedic Movie Actress.

She wore a knee-length dress that featured subtle sequins but didn't show her fabulous curves. The dress was clinched under her bust but flared down to her knees perfectly, concealing her abdomen. While that could potentially mean she is hiding a baby bump, her recent public appearances suggest otherwise as she did not gain any recent weight or shown any signs of early pregnancy.

The 43-year-old actress appeared on "Jimmy Kimmel Live" on Jan. 8 dressed in a peplum style black dress and did not appear to have any sign of a baby bump, according to Us Weekly Magazine.

Aniston was also seen flaunting her toned body while vacationing with her fiancé Justin Theroux in Cabo San Lucas, Mexico over Christmas and New Year's Day.

While relaxing in the sun, Aniston was caught by paparazzi with her toned body and flat abs in a pink bikini top with a sarong while lounging poolside at the hotel cabana.

The actress works hard to keep her body physically fit.

"I work out almost every day, at least five or six days a week," Aniston told InStyle before landing the cover of the magazine's March 2012 issue. "I do 40 minutes of cardio: spinning, running, the elliptical, or a combination of all three. Then I do Pilates one day a week, and I do yoga in addition to that, three days a week. I try to mix it up."

Aniston is also reportedly participating in the latest Hollywood diet fad known as the Honestly Healthy Alkaline Program.

The diet focuses on eating foods high in alkaline in order to keep a particular balance of the body's natural pH, according to The Daily Mail. The diet is supposedly helps with different ailments as well as contributing towards weight loss.
