Is SNOOKI’s Fiancé And Baby Daddy...

Is SNOOKI's fiancé and baby daddy JIONNI LAVALLE cheating on her? Speculation arose about a possible affair after celebrity news received reports that LaValle had been seeing his ex behind his pregnant girlfriend's back.

Seriously?

Nicole "Snooki" Polizzi is almost six months pregnant and engaged to her baby daddy, but that doesn't necessarily mean that she's about to have her happy ending in domestic guido paradise. Why? Because her future husband might be cheating on her.

According to reports, Jionni LaValle was recently photographed getting cozy with ex-flame Erica Wecksler, whom he dated before Snooki.

A source tells The National Enquirer:

"Poor little Snooki is caught up in a love triangle that she knows nothing about!"

The insider continues:

"[Jionni is] engaged to Snooki but going behind her back to contact Erica, calling and texting her. He's cheating on Snooki."

Snooki, meanwhile, has been busy writing mushy tweets about LaValle, such as "I have the hottest fiancé ever. YUM" and "Jionni makes my day."
