SEE JWOWW'S ENGAGEMENT RING!

Jersey Shore's Jenni "JWoww" Farley exclusively shows off her cushion-cut diamond engagement ring in the new issue of In Touch, on newsstands now.

"It's more than I ever expected," Jenni, 27, tells In Touch.

Roger, 37, says he spent months planning the proposal and worked with jeweler Layna Friedman to design the ring, with a cushion-cut diamond that's more than 5 carats surrounded by 2.5 carats of pink and white diamonds in a white-gold setting.

"Roger's not an average-looking guy, he's huge: his personality, his size [6'4"]. So I always said, 'I want my ring like you -- big! The bigger the better!'"

And the first person she called to share the good news? Her best friend, Nicole "Snooki" Polizzi, who will be by her pal's side as a bridesmaid or maid of honor when she walks down the aisle. "If there's anyone in this world that wanted me to be engaged more than me," Jenni says, "it'd be Nicole."
