Now that Hollywood actress Jennifer Aniston will walk down the aisle to marry her fiancé Justin Theroux, it looks like 43-year old Hollywood actress is also getting herself prepared with motherhood.

Proving that she is a good sport, the actress has turned the tables on persistent pregnancy tabloid rumors as she recently appeared pregnant in a funny advertisement video for "Smartwater." The Californian comedienne has simply starred in a spoof video while poking fun at her celebrity lifestyle in collaboration with the United States water brand.

The viral video begins with a cameo appearance from "American Idol" host Ryan Seacrest presenting a shocking news report by saying that Jennifer Aniston's home security tapes have been leaked online by an unknown source. In the video, Jennifer Aniston is seen in the kitchen with her back to the hidden camera as she removes a Velcro band from her waist that was hiding the enormous baby bump. The actress turns around to reveal a fake pregnant tummy and then drinks the water product that she is endorsing.

Meanwhile, adding more humor to the video is TV host Jimmy Kimmel's appearance as Jennifer Aniston's secret son. Kimmel asked Aniston if he could swim in the pool where two men are filling it with bottles of "Smartwater."

At the end of her day, Jennifer Aniston is seen standing in front of a mirror and says "Good night Rachel" pertaining to the character she portrayed in the hit TV show "Friends" that made her and her hairstyle famous. However, the video shows Aniston yanking off a wig to reveal her hilarious frizzy tousled locks. The video ends with the product tagline that says: "Even more refreshing than the truth."

Fans has been in doubt that Jennifer Aniston would get married again after her publicized divorce from Brad Pitt back in 2005. However, the actress became engaged to "Mulholland Drive" actor Justin Theroux after accepting his proposal on his 41st birthday last July. While Jennifer Aniston is yet to have children in real life, a family could soon be on the cards for her as she starts her new life with Justin Theroux.
