Nick Lachey Phone Call Leaves Jessica Simpson in Tears

For a couple on the outs, it sure appears that Jessica Simpson and Nick Lachey speak to each other a lot.  The pair apparently have now decided to behave like adults when it comes to dividing up their loot, but with so much at stake - including their relationship- emotions can sometimes run pretty high.

Star People Notes that a Nick Lachey phone call caused Jessica Simpson to break down in tears.

Jessica Simpson, 25, burst into tears while dining with a dozen friends at Santa Fe’s Old House restaurant on Feb. 15.

“Jessica was in a good mood, and then suddenly in the middle of dinner she got a mystery call and she completely changed,” a source tells Star People. “She got tense and burst out crying right there in front of everyone!

Then she ran out the door. Everyone looked at each other and assumed it was a call from Nick [Lachey].”
