ABC News reported that the singer is expected to give birth. Her baby was supposedly due more than a week ago.

Jessica Simpson's pregnancy has been a popular topic of conversation since the singer announced she was with child in October. Her pregnancy countdown has caused many to question just how long the singer's pregnancy would last. Some have even joked that she is 12 months pregnant.

Even other celebrities were asking when Simpson will finally have her baby girl.

Katy Perry tweeted, Has Jessica Simpson had that baby yet?! I'm getting anxious. Comedian Chelsea Handler also posted, How has jessica simpson still not given birth to this baby? I'm getting frightened.

Despite the jokes, Simpson might be laughing all the way to the bank. Photos of her newborn baby girl could fetch her as much as $500,000.

She's been so big for so long - literally and figuratively, an agency head told The Daily. The paparazzi have camped out around the Simpson compound, with her baby is due next month. But the former pop star is wise to their tactics. She keeps having decoys coming out of her house, Morgan lamented to Flash.

Jessica Simpson did give the world a look into her pregnancy when she posed naked for the cover of Elle magazine's April 2012 issue. Her nude and pregnant photo caused a deafening buzz across the Internet, with comments running the gamut from she looked gorgeous to what has she been eating?

Since the release of her Elle magazine cover, Simpson has been very vocal about her pregnancy. Fans are not the only ones patiently anticipating the birth. Surely, everyone is eager to see those first photos of Simpson's first (long-awaited) child.

With a reported 40-pound weight gain, and the inability to walk in heels, Jessica Simpson is surely just as eager to welcome her baby girl as the rest of the world.
