Nicole "Snooki" Polizzi of "Jersey Shore" fame is showing off a trimmer frame these days.

The 25-year-old reality star and mom showed off her 42-pound weight loss and her post-baby body on the cover of Us Weekly clad in a leopard-print bikini for the magazine's latest issue, which goes on sale on Friday, March 8.

Polizzi can be seen in the photo above on the cover of the magazine on the left and in an Instagram photo posted on her profile on March 4.

"When you have a baby, everything changes," Polizzi told the magazine.

The 4-foot-9-inch reality star told the magazine that she has lost 42 pounds since giving birth to son Lorenzo in late August and currently weighs 102 pounds. That is the same weight she initially slimmed down to and cited as her "goal weight" in December 2011.

"I lost it for me," she told the magazine, "but I also wanted Jionni [LaValle, her fiance] to know that I can be hot as a mom."

Lorenzo is the first child for Polizzi and LaValle. She announced her pregnancy and engagement in March 2012. Lorenzo made his debut to the public on the cover of People magazine in September 2012.

On Twitter, Polizzi spoke about the cover, noted that "hard work pays off" and thanked her trainer.

Polizzi currently appears on the second season of "Snooki & JWoww" with her "Jersey Shore" co-star Jennifer "JWoww" Farley. The second season finale is set to air on March 26.
