snooki twitpic 0329a 'Snooki' (aka Nicole Polizzi) tweets engagement pictureIt may not be her official engagement picture, but Nicole “Snooki” Polizzi tweeted a photo of herself today with boyfriend Jionni LaValle and the caption “My fiance.”

“She [is] just wrapping shooting her spinoff with J-WOWW and she took a photo and posted it,” a source tells E!. “She does it all the time. There’s nothing more to it.”

In the photo, the “Jersey Shore” star is in prime form rocking a tiger print bow atop at least two-feet of hair extensions. She’s brandishing her $55,000 engagement ring at the camera and any bump is hidden by a flowy grey sweater. Jionni, for once, looks happy. Maybe because Snooki isn’t standing on a banquette flashing her kooka.

A few minutes later, Snooks posted a solo shot with the message, “I got swagger with my pregnant self =).”
