JESSICA JABS NICK'S CRYBABY MEMORIES

Doesn't want least reminder of their time together

- 

JOLTED Jessica Simpson is reportedly seething over ex-hubby Nick Lachey's latest round of tattling, with an insider saying she's furious over his dredging up their long-ago failed marriage and threatens to spill more about him if he doesn't shut his yap.

The 51-year-old former boy-bander recently splashed headlines by claiming their MTV reality show Newlyweds pushed him to tears and hinted that the dynamic with Jessica was partly to blame.

But sources say that the 44-year-old blond bombshell is ticked — especially since she’s currently mired in a painful split from second hubby Eric Johnson, 45, dad of her kids, Maxwell, 13, Ace, 11, and Birdie, 6.
