"Nick is so worried that he's asked his lawyer to set up an emergency meeting with Jessica's attorney for some time this month to resolve this quickly" revealed an insider.

"Jessica's stalling because she knows that the lawsuits filed against her could prove to be a problem."

Sources say if Nick doesn't strike the settlement deal soon he may lose both his $5 million Bel Air mansion, plus the $3.5 million condo he's now building in Vegas.

"The divorce war is now on and reality has set in for Nick — he's sweating bullets over money," said a friend of Jessica's.

"Jessica doesn't want to leave Nick high and dry, but she's in no hurry to rush the proceedings. This is about business, not love. She's been the breadwinner in the relationship and feels Nick will be well cared for in the divorce settlement, no matter what. Jessica isn't concerned that Nick's in a cash crunch, or if the divorce takes all year."
Simpson filed for divorce Dec. 16 in Los Angeles Superior Court, citing "irreconcilable differences." She also requested that no spousal support be awarded and that her surname be officially changed back to Simpson.

Meanwhile, Lachey wants to get married again as soon as his divorce from Jessica
Simpson is finalised.
The star, who shot to fame on reality TV show 'Newlyweds' with the
singer-turned-actress, admits he would love to tie the knot again despite
his first attempt at marriage being a failure

He told America's Access Hollywood TV show: "For me, a phase was certainly
going through that emotion of not wanting to marry again. But I'm a romantic
at heart. I don't want to be a 'serial marrier' but at the same time, I just
can't imagine not being married again."
