Jennifer Aniston appeared with a fake baby bump in a promotional video for Smartwater that went viral online, but the joke certainly didn't appeal to Martha Stewart.

The famous homemaker appeared on the Today Show and told hosts Al Roker, Savannah Guthrie and Natalie Morales that she didn't like the video, in which Aniston pretends to be pregnant with triplets.

"I don't really like it. I just think it makes fun of some things and shows some bad examples to the youth of America," Stewart said. "People learn from YouTube. It's funny to a point and then it sort of steps over the bounds, I think, of sensibility."

The Smartwater ad was reportedly the brainchild of Aniston's fiancé, actor and writer Justin Theroux. He thought it would be a good idea to make light of the tabloid rumor machine that surrounds the couple's relationship and upcoming wedding.

"It was all Justin's idea. He wrote the ad and helped direct it, too. They poked fun at all the constant rumors she hears about her being pregnant," a source said.

Aniston was up for that, but Theroux wanted to take the jokes a little further than this bride-to-be cared to go.

"Justin wanted to go there with the Brangelina rumors and spoof all the stories about Jen, Brad and Ange, but Jen wouldn't let him," the insider said. "He thought it would be funny to take on the rumors once and for all and do a joke about her being secret friends with Brad and Ange, but she just couldn't do it. She can make fun of everything else but that."

Though the pregnancy in the video was a joke, Aniston has told friends she is ready to get pregnant in real life as soon as possible.

"It's no secret she wanted a baby yesterday, so they're not wasting any time," a pal said. "She's not in denial; she knows it may be difficult."
