At the launch of her latest collection on Saturday, Jessica Simpson fueled pregnancy rumors.

The singer-turned-designer appeared at a San Francisco Macy’s location in a blazer with a loose fitting black top that had chain detailing over her mid-section. With her fiance, ex-NFL player Eric Johnson in tow, Simpson raised some eyebrows with photographs of her holding a baby at the event.

In a recent story, sources close to Simpson confirmed her pregnancy, according to “In Touch.”

“She’s already having kooky cravings,” a source told the magazine.

The source described snacks containing nacho chips dipped in chocolate “which satisfy her urge for salty and sweet.”

According to “In Touch,” the source also said Simpson has also been eating cheese-flavored popcorn and drinking non-alcoholic margaritas.

The source also spoke about Simpson marrying Johnson.

“Jessica might have to take out her dress a bit,” the source reportedly told “In Touch.”

Simpson will wed on Nov. 11, the magazine also reported. After the story was released by “In Touch,” representatives for Simpson denied the claims that she was pregnant.

“She’s not pregnant,” Simpson’s spokesperson said, according to The Daily Mail.

However, the infamous entertainment television personality Joan Rivers speculated about the pregnancy on Twitter by using comedy.

"Congratulations to Jessica Simpson who reportedly has a bun in the oven,” Rivers tweeted on Saturday. “They're also saying she may be pregnant."

Other Twitter fans questioned if Simpson was pregnant with her first child after seeing her weight increase.

“Jessica Simpson got chubby,” one person tweeted.

Another Twitter user was not convinced that the singer and designer’s weight gain met a baby would follow.

“Jessica Simpson pregnant,” one person tweeted. “Loose dress proves nothing."

Simpson recently returned from a Mexican getaway with Johnson and is currently on tour for her Jessica Simpson Collection clothing line.
