Love gone bad: What happened?

The amour has ended for Christie Brinkley and Peter Cook, but maybe not for the other bust-up-couple of the month, Carmen Electra and Dave Navarro.

People magazine, in searching for answers to love gone bad, reports on its Web site that Cook, who allegedly had an affair with a teen, has chafed at being known as "Mr. Brinkley."

Meanwhile, Brinkley has taken son Jack, 11, and daughter Sailor, 8, to L.A. to be with her parents, People reports. Daughter Alexa Ray, 20, a musician whose dad is Billy Joel, didn't go; she's playing gigs in New York.

Electra and Navarro, meanwhile, "still love each other," reports People, which quotes a source who said hectic schedules were to blame for that split.

In his blog this week, Navarro wrote: "What does `amicably separated' mean? It means that Carmen and I love each other, we are and always will be best friends. ... In fact, we are supporting each other through this time. What better way to get through a tough spot than with your best friend?"
