“Jersey Shore” star Jennifer “JWoww” Far ley is being sued over the bottle design for her new tanning lotion.

College pals Eric Bramlett, Wesley Cox and Paul Rudnicki have filed suit in Oklahoma federal court, claiming that Farley — who subscribes to “Shore’s” “GTL” (gym, tan, laundry) credo — ripped off the design for Black Bronzer after reneging on a deal with them.

They say they approached Farley last year and asked her to be the celebrity spokesperson for Black Bronzer, for which they’d designed a copyrighted bottle, according to reports.

Farley allegedly was interested, but then cut off communication with the men — and launched her own line of Black Bronzer with Australian Gold, using a similar-looking bottle.

The lawsuit seeks unspecified damages.
