Pregnant Jessica Simpson's belly isn't the only thing ballooning.

"Woke up looking like the lip injection fairy visited me in the night!" the 31-year-old star tweeted Sunday. "Is this how pregnancy face begins? Yikes!"

Pregnancy face is also known as Angelina Jolie face:

The alleged singer still has some time before welcoming her first child with Eric Johnson, but she appears to be looking forward to that day on multiple levels.

Jess also tweeted that she's "looking forward to getting back into Daisy Duke shape with Mike Alexander. I forget what having a waistline feels like!"

She's also supposedly signed a deal with Weight Watchers.

For now, though, Jess is indulging in her favorite foods - "Kraft Mac n' Cheese, Pop Tarts, Cap'n Crunch. Everything's filled with sugar" - with aplomb.
