Hard work obviously pays off.

Jenni "JWoww" Farley took to Instagram on Tuesday to show off her slim physique, less than two weeks after giving birth to her second child. The 30-year-old Jersey Shore star welcomed her son, Greyson Valor Mathews, on May 5.

"I guess meal prepping, skipping desserts this whole pregnancy and only indulging with @310nutrition really paid off," Farley captioned the selfie. "Also, this isn't luck or wishing... I missed many dinner events, fun activities and lots and lots of ice cream and pizza to keep the weight off."

Despite looking super svelte, the reality star said she still has a "longgggg way to go." But she's clearly already on the right path -- Farley revealed she was previously 20 pounds heavier after giving birth to her first child, daughter Meilani, in July 2014.

"I'm going to have a kick a** comeback and push myself to be the most fit I've ever been," she wrote.

… And she has the sweet support of her husband, Roger Mathews.

"Man does it feel good to have your husband @rogermathewsnj walk in and say, 'Damn you look great,' less than 2 weeks after squishy's debut,'" Farley admitted.

Last November, Farley said she doesn't plan to give birth to any more children.

"I am so done with pregnancy," she told Fit Pregnancy, "but maybe in the near future we can adopt."

"Nicole ['Snooki' Polizzi] was adopted and my mom was adopted," she added. "I've always felt a special connection to that. I would love to give a baby who needs it a nice home to come home to and be loved."
