Reality TV star Snooki says she will have a wedding themed on "The Great Gatsby".

The 26-year-old is getting ready to wed fiance Jionni LaValle and has chosen the special theme for her nuptials, reports femalefirst.co.uk.

"It's a 'Great Gatsby' theme, with black and gold," Snooki told In Touch Weekly magazine.

She has already picked up a wedding gown and party dress for the reception and says neither of the outfits are influenced by her "Jersey Shore" style.

"I got my dresses. Everyone expects me to wear glitter and leopard (print) and I'm like, 'Maybe, if I got married four years ago'. I got an elegant ballgown for the church, and a mermaid style dress with a poufy train for the reception," Snooki said.
