Snooki's fiance insecure?

'Jersey Shore' star Snooki's fiance Jionni LaValle is reportedly worried about their relationship.
Snooki, real name Nicole Polizzi, is getting so much attention during her stint on 'Dancing with the Stars' that LaValle, 26, fears she will be swept off her feet by someone else before he gets the chance to walk her down the aisle, reported Showbizspy.
Snooki and LaValle got engaged in March 2012.
"Her career is really taking off. She has been getting calls about starring in her own sitcom, and her agents are receiving scripts from movie producers," a source said.
LaValle keeps asking her to pick a wedding date, but Snooki always finds reasons to delay.

"Now she wants to hold off until the house they are building is complete. It is always something. Jionni is terrified of losing her. He is showering her with gifts of expensive jewelry, flowers and sexy lingerie.
"He is desperate for her to set a wedding date before some other guy steals her away. His big fear is that she will fall for a young Hollywood star who is hunkier and wealthier than he is," the source added.
