Jessica Simpson still hasn’t given birth and even fellow stars are getting impatient

Jessica Simpson is due to give birth any day now but she is still waiting to go into labor.

While Jessica Simpson, 31, must be getting incredibly impatient, her fellow stars are also eager for the baby to be born.

Katy Perry and Chelsea Handler each took to their Twitter pages to wonder why Jessica Simpson still hasn’t given birth.

The pop star and comedienne even expressed concern as they respectively claimed to be “anxious” and “frightened” for Jessica Simpson.

Katy Perry last night tweeted: “Has Jessica Simpson had that baby yet?! I’m getting anxious.”

And Chelsea Handler echoed the sentiment this morning when she posted on her own page: “How has jessica simpson still not given birth to this baby? I’m getting frightened.”

While Katy Perry and Chelsea Handler have been worrying for the pregnant celebrity, not all stars are quite so sympathetic.

Jersey Shore star Nicole “Snooki” Polizzi has revealed she’s avoiding fatty foods in a bid to keep her pregnancy weight in check.

Nicole Polizzi, 24, says, rather unkindly, that Jessica Simpson served as a warning to her and added she “would die” if she got as big as she did.

The Jersey Shore star is expecting her first child with her fiancé Jionni LaValle.

“I would die if I were her size,” she told Us Weekly, adding that she won’t be enjoying buttered Pop Tarts and treats like Jessica.

“She said she indulged in everything that she wanted. I’m trying to each healthy – fruits, lots of jelly and Italian ices. Nothing fattening at all.”

Jessica Simpson is due to give birth to a daughter with fiancé Eric Johnson.
