Where's the bump! Former "Jersey Shore" star Jenni "Jwoww" Farley is halfway through her pregnancy, but you would never know it by looking at her.
The momma-to-be showed off her barely-there baby bump on Instagram while promoting nutrition shakes.
"This is my baby bump at 20 weeks!!!" she captioned a side-by-side image of her flat tummy and another of her drinking a shake. "Everyone has been asking me how I stay so fit even during my pregnancy and my secret is @310nutrition shakes!"
In the same post, she shared her shake diet secret with her 3.9 million followers.
"I have one in the morning and one as a late night snack! Soo yummy!," she wrote. "#fitpregnancy #sp #310nutrition #310shake."
In October, Jwoww married longtime boyfriend Roger Matthews. At the wedding party, the duo, already parents to 1-year-old daughter Meilani, announced that they were expecting their second child together.
It was later revealed that they were having a baby boy. However, he isn't showing much of himself in Jwoww's belly just yet. In her Instagram post, though, Jwoww said she anticipates ballooning up fairly quickly.
"Don't worry," she wrote, "I'm gonna pop big time."
