A word to Jessica Simpson's personal assistant: Loose lips sink ships.
Lowdown hears that the twentysomething CaCee (pronounced "Casey") Cobb - who now finds herself the object of a quasi-custody battle between Jessica and her estranged husband, Nick Lachey - has been blabbing to friends about Simpson's alleged infidelities and voicing her sympathy for Nick's plight.
"CaCee can't get past the fact that Jessica cheated," reports a Lowdown spy close to the situation. "She feels badly for Nick and is very vocal about missing him. She saw Jessica abuse him all along. Ever since 'Dukes of Hazzard,' Jessica hasn't been good to Nick, and no one saw this more clearly then CaCee."
While it has been widely speculated in print that Simpson had affairs with her "Dukes" co-star Johnny Knoxville and "Jackass" alum Bam Margera, the Lowdown insider claimed that Jessica also had a fling with Maroon 5 front man Adam Levine.
Levine's rep denied it yesterday.
"CaCee knows her loyalty belongs to Jessica, but she still resents her for hurting Nick so much," said the spy.
Cobb apparently hasn't been silenced, even by such extravagant gifts from Simpson as the $40,000 BMW bestowed a few days before Simpson announced her separation from Lachey.
But yesterday Simpson's spinmeister Rob Shuter insisted that everything is peaches and cream.
"None of this is true," he E-mailed. "Saturday night was CaCee's birthday. We all had dinner and then went out to the Roosevelt Hotel [in L.A.]. Jess paid for everything. Jess also bought CaCee a vintage Rolex watch. Jess and CaCee love each other. CaCee is still friends with Nick."
Lachey's recently hired crisis manager, Ken Sunshine, zipped his lips
Jess sure gets around
