Jenni "JWoww" Farley says she had a miscarriage in 2011.
The 32-year-old said on Thursday's episode of "Jersey Shore Family Vacation" that she "lost a baby" prior to filming "Jersey Shore" Season 4, which took place in Italy.
"Three or four weeks before Italy, my grandmother passed, and me and Roger actually lost a baby," she told co-star Mike "The Situation" Sorrentino, referencing her now-husband, Roger Matthews. "Not a lot of people know."
Farley said she was consequently a "mess" during the season, in part because she was put on medication.
"They put me on medication because of it, I couldn't handle life," she recalled. "But the medication, it was like Xanax. It would would take me down ... Then I started taking uppers."
Farley later gave birth to daughter Meilani Alexandra in 2014 and son Greyson Valor in 2016. Farley posted a slideshow on Instagram of her two kids during their Easter celebration this month.
"@greysonmathews never lets me take a pic," she captioned the photos.
"Jersey Shore" initially had a six-season run on MTV from 2009 to 2012.
Farley, Sorrentino and their co-stars Nicole "Snooki" Polizzi, Paul "Pauly D" DelVecchio, Ronnie Ortiz-Magro, Vinny Guadagnino and Deena Nicole Cortese returned to star on "Jersey Shore Family Vacation," which premiered this month.
