PHOTOS: J-WOWW A Midriff Mama By The Shore

Well someone's been doing their crunches.

Jersey Shore's Jenni “J-WOWW” Farley showed she's a lean, mean GTL machine while taking a stroll in Seaside Heights, New Jersey Tuesday, and RadarOnline.com has all the pics for you.

The 23-year-old reality star is clearly taking great care of her body, showing off a lean and taut midriff in her sports bra and sweatpants combination.

J-WOWW's had some ups-and-downs in her love life as of late, ending her relationship with ex-boyfriend Tom Lippolis, and starting a new one with oil truck driver Roger Mathews.
