Snooki's ultrasound shows unborn baby.Snooki did NOT secretly get married to her baby daddy Jionni LaValle … and she did NOT secretly take the guy’s name either — despite what her ultrasound says — sources tell TMZ.

      In case you missed Thursday night’s episode of “Snooki Jwoww” — the Snookster unveiled her highly-anticipated ultrasound … and Snooki’s name is listed as “Nicole LaValle.”

      But Snooki sources tell TMZ, the ultrasound is WRONG — because Snooki’s real name is still legally “Nicole Polizzi.” The doctor’s office simply entered the wrong name by accident.

      And for all you conspiracy theorists — the source adds, “Snooki is 100% not married … yet.”

      Case closed.
