Snooki has come a long way since her Jersey Shore pouf days. The reality star looked perfectly glam just one hour after giving birth to her second child, daughter Giovanna, this past September.

“Aw only an hour old my nugget! She's now 4 months and a chunker! So in love with my princess,” Snooki captioned a throwback photo of herself dolled up in a hospital bed holding her newborn on Monday, Feb. 2, proving she looked that good after delivering her baby girl.

The former party girl’s little princess joined her firstborn, son Lorenzo, on Sept. 26 and leading up to her arrival, Snooki didn’t mess around.

"My first pregnancy, I didn't do anything. I just sat and ate on the couch and I was literally a whale,” she told Us in April 2014. “I was so negative, because I just didn't feel good at all. With this pregnancy, I'm working out and eating healthy. I feel better about life."

And work out she did. The 26-year-old busted it out in the gym, even doing squats and lifting weights at 8-months-pregnant, and managed to slip into a wedding dress to marry husband Jionni LaValle in November 2014.
